Tou nave a heterozygote male, and you know that his dad was homozygous dominant for both

Step 1

Inheritance is the process of transmission of traits from parents to offspring. Traits are controlled by contrasting pairs of alleles of a gene on a chromosome. When alleles of two genes are present on different chromosomes, they are inherited independently. When the two alleles are present on the same chromosome at proximity, they are inherited together and thus are linked.

Step 2

In the given question, the dog under consideration is heterozygous for both the traits. Its father is heterozygous for both the traits while mother is homozygous for recessive traits. The dog is married with a female who is homozygous for recessive traits.

a) The genotype of the dog is BbWw and the genotype of the female is bbww. Since, the alleles are linked, a small number of recombination can also occur. The probable genotype of the gametes is shown below:
