In horses, the allele for a black coat (B) is dominant over the allele for a brown coat (b). A cross between a black horse and a

GaryK [48]

Answer:

Bb X bb

Explanation:

It is given that the allele B for the black coat is dominant over allele b for a brown coat.

A dominant allele always leads to the expression of the dominant trait in the heterozygous condition.

When a black and brown horse is crossed as given in the question and the result is a brown foal, then the genotype of the brown foal must be bb as the brown coat is a recessive trait.

Since each parent contributes one allele each for a given gene, the black horse must have b allele, and hence must be heterozygous Bb.
The cross is shown in the punnett square.
