A dog breeder crosses two dogs that are heterozygous for brown coats. Some of the puppies have brown coats, and some have black coats.

Assuming that coat color is controlled by a single gene, which of the following statements is most likely true?

CORRECT (SELECTED)
The allele for brown coat is dominant to the allele for black coat.

Because some of the puppies have black coats, we know the parents must be heterozygous.

The statement which is most likely true according to the information given above is the allele for the brown coat is dominant to the allele for the black coat.

What is Allele?

An Allele may be defined as one or two or alternative more versions of a DNA sequence at a given genomic location.

The allele for the brown coat is dominant to the allele for the black coat. This is because when a dog breeder crosses two dogs that are heterozygous for brown coats, it means Bb × Bb. It produces the offspring with the genotypes BB, Bb, Bb, and bb.

Therefore, the statement which is most likely true according to the information given above is the allele for the brown coat is dominant to the allele for the black coat.
