The Merle gene is a game-changer for Chihuahua breeders and owners. It's a gene modifier that affects more than just coat color, influencing skin pigment and eye color as well.

The Merle gene is an incompletely dominant gene, meaning it doesn't completely override its recessive counterpart. This results in a unique coat pattern with irregular patches of dark-colored fur on a light-colored base.

The Merle gene affects the distribution of eumelanin, which controls black color in a Chihuahua's coat, diluting areas of the coat that are pigmented with eumelanin. This results in blue or red merle Chihuahuas, depending on the shade of their dark-colored fur.

Here's a breakdown of how the Merle gene is inherited in Chihuahuas:

Remember, the presence of the Merle gene can also lead to the birth of ghost Merles, which are Chihuahuas that carry the Merle gene but don't display the Merle coat pattern. If you suspect your Chihuahua is a ghost Merle, it's essential to have them genetically tested to ensure you're being an ethical owner and taking responsibility for their unique trait.

The Merle gene is a gene modifier that affects how other genes express themselves. This means it has a ripple effect on various aspects of a Chihuahua's appearance.

The Merle gene doesn't just stop at coat color; it can also influence skin pigment, resulting in light and dark spots beneath the coat.

The merle gene affects the distribution of pigment within a Chihuahua's coat. It specifically dilutes areas of the coat that are pigmented with eumelanin, resulting in irregular patches of dark-colored fur on a light-colored base.

The merle gene affects the distribution of eumelanin, which controls the black color in a Chihuahua's coat. Eumelanin is one of two pigments that govern a Chihuahua's coat color, the other being phaeomelanin.

Chihuahuas can have a wide variety of coat colors due to just these two pigments. The merle gene doesn't override the non-merle allele entirely, resulting in both genes being partially expressed when paired together.

Merle Chihuahuas can be classified as blue or red depending on the particular shade of their dark-colored fur. Blue merles have patches of black fur, while red merles have patches of brown or copper-colored fur.

Here's a breakdown of the two main types of merle Chihuahuas:

The merle gene affects more than just coat color. It can also affect a dog's skin pigment and eye color.

The merle gene is responsible for the merle pattern in Chihuahuas and other breeds. It's a mutation of the non-merle allele (m) gene.

Chihuahuas inherit pairs of genes, one from each parent. All merle Chihuahuas have the Mm genotype, inheriting the merle gene from one parent and the recessive allele from the other.

The merle allele is an incompletely dominant gene, whereas the non-merle allele is a recessive gene. This means the merle gene doesn't override its recessive counterpart entirely.

A team of geneticists discovered the merle gene in 2006 while researching merle Shelties. They found extra DNA tacked onto the PMEL17 gene, which affects pigmentation.

The PMEL17 gene is responsible for pigmentation in dogs. Merle Chihuahuas and other merle dogs exhibit the same genetic mutation as merle Shelties.

Here's a quick rundown of how the merle gene affects breeding:

Merle Chihuahuas are known for their unique coat patterns, which can be a mix of gray, brown, and black.

Their coats can also have a blue or red tint, depending on the genetics of the parents.

Merle Chihuahuas are more likely than other breeds to develop hearing and vision problems. This is due to the merle gene modifier.

The merle gene within the Chihuahua breed comes with an increased risk of congenital health issues. These issues can include being born deaf, blind, or both.

Merle Chihuahuas may also be more sensitive to the sun, especially those with shorthaired or smooth coats. This is because they have less fur to protect them.

Breeding two Merle parents together should never be done, as the risks for the pups being born with these conditions are extremely high.

Merle Chihuahuas have a higher risk of being born with hearing and vision problems.

The merle gene also makes dogs more sensitive to sunlight, especially those with shorthaired or smooth coats.

Some Merle Chihuahuas may develop full or partial deafness, skeletal problems, heart problems, and reproductive issues.

Breeding two Merle parents together is not recommended, as the risk of health problems in their puppies is extremely high.
