why do some french bulldogs have blue eyes
Eye color genetics:
There are three major genes that control eye color: EYE, which codes for the pigment melanin HERC2, which codes for the enzyme tyrosinase OCA2, which codes for the pigment oculocutaneous albinism These genes can interact in various ways to produce the six different eye colors: blue, green, brown, hazel, amber, and violet.The most common eye color is brown, which is the result of a combination of the EYE and HERC2 genes. A person with two copies of the brown allele will have brown eyes, while a person with one copy of the brown allele and one copy of the green allele will have hazel eyes.Green eyes are the result of a combination of the EYE and HERC2 genes and the OCA2 gene. A person with two copies of the green allele will have green eyes, while a person
Breed-specific eye colors:
There are many different eye colors found in different breeds of dogs. Some are common, while others are quite rare. Each breed of dog has its own specific eye color that is characteristic of that breed.Many people think that all blue-eyed dogs are the same breed, but this is not the case.

Blue eyes in French Bulldogs: :
The gene for blue eyes is recessive, which means that a dog must inherit two copies of the gene in order to have blue eyes. If a dog only has one copy of the gene, the eyes will be some other color. French Bulldogs are typically bred to have brown eyes, so the gene for blue eyes is not very common in this breed.
