What Features Classify American Bullies as Having Merle Coats?

American Bullies that have coats of merle are easy to recognize due to the hair-like patches that are present in their coats with distinctive patterns of discolored shades (pigments).

Although some may refer to American Bullies with the merle mutation, which can be seen in a variety of hues, there are three which are the most commonly used. These are ‘blue’, ‘red’ and ‘cryptic’ merles.

1.) Blue Merles

While they’re referred to as ‘Blue Merles’, the reality is that the color in American Bully is actually gray with black patches. In certain lighting types of the blue merle’s coat may appear blue and that’s the reason behind the confusion.

Their coats are very like the tricolor American Bully because it typically consists of white, tan, and black. However, the black can be faded and appear grey. Bi-blue can also be an option, the case when a blue Merle does not have any tanning in any way.

2.) Red Merles

More of a mottled pattern than Blue Merles, Red Merles tend to be more black and tan and can often display quite dark areas that are dark in hue (although they can be very pale too).

Red merles are more common than blue merles due to the fact that while all breeds are capable of producing blue Merles, only a tiny number of breeds are able to produce red. Red merles may be spotted with tan marks in their coats or not, but can still be referred to as red merles.

3.) Cryptic Merles

Sometimes, you’ll find the American Bully that appears to have a normal coat. However, it is Merle, and can transfer the merle genes to their puppies if they are bred. The reason behind this unique coat, as of now it is not known. The merle of this type of American Bully is known as the mysterious merle.

This could mean that it’s unclear, mysterious, or difficult to comprehend why they carry the gene merle but don’t reveal it.

The most fascinating thing about the merle gene is the fact that it’s dominant, and therefore it is a dominant breed. American bully that has the merle gene is likely to inherit it through one parent. They are almost guaranteed to transmit it to at the very least some of their puppies.

What is the Difference Between a Single Merle and a Double Merle?

Every dog that has the merle mutation is born with the Mm genotype. This is due to something known as “the M allele” (an allele is a different variant or mutation of the normal gene) and also the reality that a merle carries only one replica of the allele M.

This, in particular, is what causes the unique color pattern. An American Bully which does not have merle would be the genotype mm. On the other hand, one with one merle gene will have the Mm gene.

One of the most heated discussions within the American Bully community at the moment is whether a merle and a different one should be bred together and could result in, and often does, to a double merle also known as MM genotype.

If two dogs bearing the merle gene breed approximately 1/4 are likely to be MM genotypes, that is, as previously mentioned, known as double-merle, as well as a Double-dapple.

It is interesting to note that double-merles don’t appear to be merles and instead have coats that are predominantly white with tiny patches of merle scattered around.

The reason behind this is fascinating. If an American Bully inherits a single Merle gene (Mm), it creates the unique marbling/lightening effect. It also causes a multitude of light spots scattered across the coat’s solid color.

However, the moment an American bully is born with two Merle genes (MM), this distinctive effect is increased by creating a number of bright spots that cause the coat to be like an even white color, instead of marbled. This is the result of the absence of the normal pigmentation the mutation can cause.

Double Merles are created by mixing two blue merles or two red merles as well as a red and blue merle. The probability of having a double merle created is about 25% or more or less.

The reason of crossing two bulls together has become one of the main points of contention in the American Bully community is because they do not have the normal pigmentation. They ought to be double merles are more vulnerable to serious health issues like blindness, deafness, or both.

It’s not every time but, as every American Bully lover will surely admit, every time happens is too many instances. If you want to know more about this, visit https://www.burrnationk9s.com/.
