A dog that is homozygous dominant for Tyrp1 and homozygous recessive for Mc1r will be what color?
Question
A dog that is homozygous dominant for Tyrp1 and homozygous recessive for Mc1r will be what color?
Solution
The color of a dog's coat is determined by multiple genes, including Tyrp1 and Mc1r.
Tyrp1 is a gene that affects the production of black pigment. If a dog is homozygous dominant for Tyrp1 (meaning it has two copies of the dominant allele), it will produce black pigment.
Mc1r is a gene that affects the distribution of pigment in the dog's coat. If a dog is homozygous recessive for Mc1r (meaning it has two copies of the recessive allele), it will have a uniform distribution of pigment.
Therefore, a dog that is homozygous dominant for Tyrp1 and homozygous recessive for Mc1r will be uniformly black.
