How can I tell if my dogs merle is blue?
The merle gene modifies the dark pigment in the eyes, occasionally changing dark eyes to blue, or part of the eye to be colored blue. Since merle causes random modifications, however, both dark-eyed, blue-eyed, and odd-colored eyes are possible. Pigmentation on paw pads and nose may be mottled by pink.
Does merle cause blue eyes?
Blue Irises & Merle Genes The merle gene typically causes a lightening of pigment in the coat as well as in the dog's irises. Most dogs have brown eyes, so their eyes have a lot of pigment. Dogs who have blue irises have less pigment. Therefore, blue eyes can be a sign of a dog carrying merle genes.
How do you tell if a dog is a double merle?
Dogs with the double merle gene may be/have:
- All white in color, or have patches of merle/mottled coloring on the top half of their body – their head, back, and base of the tail.
- Light-colored paw pads.
- Have light blue, green or brown eyes, perhaps even eyes that are different colors.
How do I know if my dog has the merle gene?
The merle gene creates mottled patches of color in a solid or piebald coat, blue or odd-colored eyes, and affects skin pigment. ... Recessive red dogs can also be affected by merle, but the patches are either hardly seen or (if the dog is a clear, recessive red) are not visible at all.
What does a blue merle look like?
Some blue merle dogs will have a mostly gray-blue coat with a few small, black patches. The most common merle pattern and the one described in most breed standards is a coat that is approximately 50 percent merle, or gray-blue, and 50 percent black patches.
How do you tell if a puppy will have blue eyes?
You can usually tell if your puppy will have blue eyes permanently by taking a look at the eye color of its parents. Furthermore, the type of breed the puppy belongs to can also affect this, with certain breeds being more likely to have brown eyes compared to other breeds.
What gene causes blue eyes in dogs?
In short, we discovered a genetic mutation, specifically a duplication of DNA sequence near ALX4 (a gene on dog chromosome 18 involved in craniofacial, skin, and hair follicle development) that explains why some dogs have blue eyes.
Why do some merle dogs have blue eyes?
- This Merle coats are caused by genes, which may also affect eye colors, coats, and more. The color is actually a recessive gene and it is not something that you can find in all the dogs that are going to be blue. You will have to know how many breeds that have this gene and where the other dogs are that is a good mix of the two different colors.
Can a merle gene anomaly cause blindness in a dog?
- The blue appearing in your dog’s eye can be a part of an eye that is otherwise brown and won’t impact his site. On the most severe end, the Merle gene anomaly can cause blindness. The front or back of your dog’s eye can be impacted; though the condition can impact both parts.
How many copies of the merle gene does a dog have?
- In each dog, there are two copies of a gene; one from each of his parents. We will call the Merle gene “m” and the non-merle gene “M”. If your dog gets two copies of m, the gene for Merle, it is considered homozygous (mm) or double merle. A dog with two merle genes will be mainly white in color.
Can a blue merle dog breed with another dog?
- The Merle gene has been shown to be closely related to its lack of commonness in the breed. If you want to breed with another color, be sure to check with the Kennel Club to make sure that the dog that you are breeding with can carry the Blue Merle gene.
