Answer 2

The genotype of a father is WW. Thus, he will produce only one type of gamete that is, W.

The genotype of a mother is Ww, Thus, she will produce two types of gametes. One gamete would contain W and the other would contain w.

The cross would result in the production of offspring with two types of genotypes WW and Ww in ratio 1:1.

The same is shown in the form of Punnett square below.
