Mayo Clinic Q and A: Genetics and weight
DEAR MAYO CLINIC: How big of a role does genetics play in weight? If you are predisposed to obesity because of your genes, how effective can a diet or other weight-loss strategies really be in the long run?
ANSWER: Genetics play a role in determining your weight. But thats not the whole story. Environment, lifestyle and healthy choices still contribute a great deal to how much you weigh. And your genes also make a difference in the type of weight-loss strategies that may work best for you. When deciding how to move forward with achieving weight loss, all of these factors must be considered.
Obesity is a significant concern in the U.S. According to the Centers for Disease Control and Prevention, or CDC, two-thirds of Americans are overweight, and one-third of people in this country are obese. Thats a problem, because obesity is associated with many serious health concerns, including diabetes, heart disease and stroke. The CDC also estimates that the annual medical cost of obesity in the U.S. is about $150 billion per year.
With two-thirds of the U.S. population overweight, its clear that a better way to manage weight is needed. Rather than approaching weight loss as if everyone has the same problem, a more individualized strategy is needed.
Genetic analysis can be useful for creating an individual approach to weight loss. For example, your genetics can make a difference in factors such as how full you feel as you eat, your appetite levels, and how your body uses energy and burns calories. All of those energy expenditure, level of fullness, appetite, body composition and gastric emptying can be measured and evaluated. Specific types of testing also can reveal how your body responds to certain medications.
That information can be very valuable in crafting a weight-loss program that fits your bodys needs and make it more likely that you will be able to lose weight and keep it off over the long term.
An example of how this type of careful evaluation can make a difference can be seen in the use of weight-loss medication. Currently, the U.S. Food and Drug Administration has approved five medications for weight loss in people who are obese. Usually, when these medications are used, about 30 percent of people will not respond, seeing little or no effect on weight loss due to the medication. About 30 percent will respond in a modest way. And about 30 percent will have a significant weight-loss response equaling a loss of more than 10 percent of total body weight in a year.
Recent studies show that, depending in part on an individuals makeup, health care providers may someday be able to use specific testing and genetic analysis to select the right medication for the right patient. In the future, genetics also may help to show how effective weight-loss procedures, such as gastric bypass surgery or placement of an intragastric balloon, might be for an individual.
It is important to note, however, that medical treatment for weight loss, such as medication and surgery, must be accompanied by lifestyle changes that include a healthy diet and regular exercise. Without dedicated attention and effort put into those areas, no weight-loss intervention can succeed over time. Dr. Andres Acosta, Gastroenterology and Hepatology, Mayo Clinic, Rochester, Minnesota
Understanding Yorkie Color Change and Its Causes
Do Yorkies change colors? This is a common question among Yorkshire Terrier owners, and the answer is yes! Yorkies do indeed undergo color changes as they age. Many Yorkie puppies are born with a dark coat color, often black or black with some tan markings. However, as they grow older, their coat can lighten or darken, resulting in a different color appearance.
When do Yorkies change color? Yorkies usually experience their most significant color changes during the first year of their lives. The extent and timing of these color changes can vary from dog to dog. Some Yorkies may begin to lighten or darken as early as a few weeks old, while others may not go through noticeable color changes until they are several months old.
What causes Yorkshire Terrier color change? The exact cause of Yorkie color change is not fully understood, but genetics is believed to play a significant role. Yorkshire Terriers have a gene called a sable gene, which is responsible for their color changes. This gene can cause the hair shafts to produce different pigments, leading to variations in coat color.
Yorkies change color as they age? Yes, Yorkies can continue to undergo color changes even as they reach adulthood. It is not uncommon for a Yorkies coat to keep evolving until they are around two years old. It is essential to note that these color changes do not indicate any health issues and are just a natural part of the breeds development.
In conclusion, Yorkie color change is a fascinating phenomenon that occurs as these adorable dogs mature. Understanding the process and accepting the variations in coat color can help Yorkie owners appreciate the uniqueness and beauty of their pets. So, if you notice your Yorkies coat changing, embrace the transformation and cherish your little companions ever-evolving appearance!
What Causes Yorkie Color Change?
Yorkshire Terriers, or Yorkies, are known for their beautiful and distinct coat colors. However, it is not uncommon for Yorkies to experience color changes as they mature. These changes can be subtle or dramatic and can occur at various stages of their lives.
- When do Yorkies change color?
Yorkies typically undergo their first color change when they are around six to nine months old. This is known as the puppy coat transition. During this time, the puppys soft and fluffy coat transforms into their adult coat, which usually has a different color and texture.
- Do Yorkies change color as they age?
Yes, Yorkies can continue to experience color changes even after their puppy coat transition. Some Yorkies may darken or lighten in color as they get older. This can happen gradually over time or suddenly, depending on the individual dog.
- Do Yorkies change colors?
Yes, Yorkies are known for their ability to change colors. This is due to a genetic trait called fading gene, which can cause their coat to lighten or darken. Fading gene can be inherited from one or both parents, and it can affect the intensity of the coat color.
- Why do Yorkies change colors?
The exact reasons for Yorkie color change are not fully understood. It is thought to be a combination of genetic factors and hormonal changes. Additionally, factors such as sun exposure, diet, and overall health can also play a role in color changes.
- Yorkshire Terrier color change
Color changes in Yorkshire Terriers can range from subtle variations in shade to more significant shifts in color. Some common color changes include darkening of the coat, lightening of the coat, or changes in color distribution. These changes can add to the unique beauty of the Yorkie breed.
In conclusion, Yorkies are prone to color changes as they age. These changes can occur at different stages of their lives and can be influenced by various factors. Its important for Yorkie owners to embrace these color changes as part of their pets individuality and appreciate the unique beauty that comes with them.
The Role of Genetics
The Yorkshire Terrier breed is known for its beautiful coat, which goes through a significant color change as the dog ages. Understanding why and how this color change occurs requires an understanding of the role genetics play in determining a Yorkies coat color.
Yorkshire Terriers are born with a coat that is predominantly black or dark steel blue with tan markings. However, as they grow older, their coat undergoes a transformation, and the black or blue portions of their coat gradually fade or lighten in color. This change is primarily determined by the presence of specific genes that control pigmentation.
There are two main genes that influence a Yorkshire Terriers coat color: the B locus gene and the E locus gene. The B locus gene determines the intensity of the black or blue color, while the E locus gene determines the production of eumelanin, which is responsible for the dark pigment in the coat.
When a Yorkshire Terrier is born, it inherits two copies of each gene one from its mother and one from its father. The combination of these genes determines the color of the dogs coat. If both copies of the B locus gene are present, the dog will have a black coat. If only one copy is present, the dogs coat will be blue. If both copies are missing, the coat may be chocolate or liver-colored.
Similarly, the presence or absence of the E locus gene determines whether a Yorkie will have a dark or light coat. If the gene is present, eumelanin production is normal, and the coat will be darker. If the gene is missing, eumelanin production is reduced, resulting in a lighter coat.
Its important to note that not all Yorkies will go through a dramatic color change. Some may retain their original coat color throughout their lives, while others may experience only subtle changes. Furthermore, other genes can also influence coat color and pattern, leading to a wide variety of color combinations in Yorkshire Terriers.
In conclusion, the color change observed in Yorkshire Terriers is a result of the interplay between various genes that control pigmentation. Understanding the role of genetics is crucial to comprehending why and how these color changes occur.
Age-Related Color Changes
Yorkshire Terriers, also known as Yorkies, are small and elegant dogs that are beloved for their beautiful coat. One fascinating aspect of owning a Yorkie is that their coat color can change as they age.
As puppies, Yorkies usually have a different coat color compared to when they reach adulthood. They are often born with a dark coat or with a combination of colors. However, as they grow older, their coat can undergo color changes, and different shades and patterns may appear.
There are a few reasons why Yorkies change colors as they age. One reason is genetics. The genes that determine a Yorkies coat color may become more prominent or less pronounced as the dog matures. This can lead to a shift in the distribution of melanin, the pigment responsible for coat color.
In addition to genetics, environmental factors can also play a role in the color change of Yorkies. Exposure to sunlight, air, and other environmental elements over time can cause the coat to fade or develop new shades.
Its important to note that not all Yorkies will experience significant color changes as they age. Some may exhibit subtle variations in color, while others may have more dramatic changes.
Overall, the color change in Yorkies is a natural process and should not cause concern. It adds to the uniqueness and charm of each individual dog. So, if you have a Yorkie, dont be surprised if their coat color evolves over time!
Environmental Factors
Yorkies, like many other dog breeds, can undergo color changes as they age. While genetics play a significant role in determining their coat color, environmental factors can also influence the changes in their appearance.
Exposure to sunlight
One of the environmental factors that can affect the color change in Yorkies is exposure to sunlight. The ultraviolet (UV) rays from the sun can lighten the fur color, especially in areas that are constantly exposed. This is commonly seen in Yorkies with dark coats, which may gradually become lighter over time.
Seasonal changes
Seasons can also contribute to the color change in Yorkies. Just like how human hair can appear lighter in the summer due to increased sun exposure, the same applies to a Yorkies coat. During the winter months, when there is less sunlight, their coats may appear darker or more vibrant in color.
Additionally, the temperature can also affect the coat color. Yorkies have a double coat, and the undercoat tends to become thicker in colder weather. This can cause the topcoat to appear darker and more rich in color.
Its worth noting that the extent of color change can vary from dog to dog. Some Yorkies may experience more significant changes, while others may only have subtle variations in their coat color.
Understanding why Yorkies change colors and when it occurs can help pet owners anticipate and appreciate these natural transformations in their beloved furry companions.
Health Conditions
While the color change in Yorkshire Terriers is a natural process, it is important to keep an eye out for any underlying health conditions that may cause abnormal color changes. Here are some common health conditions that can affect the color of a Yorkies coat:
- Premature graying Yorkies, like humans, can experience premature graying of the hair due to genetics or stress. If you notice your Yorkies coat turning gray at a young age, it is recommended to consult with a veterinarian to rule out any underlying health issues.
- Hyperpigmentation Some Yorkies may develop patches of darker or discolored fur due to a condition called hyperpigmentation. This can be caused by hormonal imbalances, allergies, or other skin conditions. If you notice any abnormal changes in your Yorkies coat color, it is best to seek veterinary advice.
- Inflammation or infection Skin inflammation or infection can also lead to changes in the color of a Yorkies coat. If you observe redness, swelling, or an unusual odor coming from your Yorkies skin or coat, it is important to consult a veterinarian as these may be signs of an underlying health issue.
- Nutritional deficiencies Poor nutrition can affect the health and appearance of a Yorkies coat. A lack of essential nutrients, such as vitamins, minerals, and fatty acids, can lead to dullness, thinning, or changes in color. Providing a balanced and nutritious diet is crucial for maintaining a healthy coat.
- Age-related changes As Yorkies age, their coat color can naturally change due to the gradual loss of pigmentation. This is a normal part of the aging process and is not usually a cause for concern. However, it is important to monitor any other accompanying changes in your Yorkies health as they age.
It is always advisable to consult with a veterinarian if you have any concerns about your Yorkies coat color or overall health. They can provide a proper diagnosis and recommend any necessary treatments or dietary adjustments.
Understanding the Pigment Melanin
Melanin is the pigment that gives color to the hair, skin, and eyes of living organisms, including Yorkies. It is responsible for the different shades and patterns of fur that we see in these dogs.
Yorkies change color as part of their natural development. When Yorkies are born, they often have a completely different color of fur compared to when they are adults. This color change is primarily due to the presence of melanin.
As Yorkies age, their production of melanin might decrease, causing their fur color to lighten. This can result in a change in shade or even a complete shift in color. For example, a Yorkie that was once jet black as a puppy may become a lighter shade of gray or silver as it grows older.
Additionally, external factors such as sunlight and grooming practices can also influence the melanin production in Yorkies. Sunlight can cause the fur color to fade or even turn a different shade, while certain grooming products may contain chemicals that affect melanin production.
It is important to note that not all Yorkies change colors. Some Yorkies may maintain their original fur color throughout their lives, while others may experience subtle changes. The degree to which a Yorkie changes color can vary from dog to dog.
Understanding the role of melanin in Yorkie color change is essential for Yorkie owners to recognize and appreciate the unique transformation their furry companions may undergo as they age. It adds to the charm and individuality of each Yorkie, making them even more special.
