A shaggy heterozygous rabbit was crossed with a smooth-haired rabbit. Determine the phenotypes and genotypes

A shaggy heterozygous rabbit was crossed with a smooth-haired rabbit. Determine the phenotypes and genotypes of the F1 and F2 hybrid offspring (furry coat dominates over smooth coat).

Considering that the hairy hair gene is dominant, a heterozygous hairy rabbit will have the Aa genotype and will produce two gamete varieties: A and a, a smooth-haired male will have aa genotype and will produce only one gamete variety: a. As a result of crossing in the first generation, we get a splitting of shaggy and smooth-haired rabbits 1: 1 (Aa: aa). To get the descendants of the second generation, we cross the descendants of the first generation among ourselves (Aa * aa). In the second generation, we get a similar splitting among rabbits, because the genotypes of the parents are identical to the genotypes of the original pair of rabbits.

Answer: in F1, the split is 1: 1 by phenotype and genotype (furry: smooth-haired and Aa: aa, respectively).

in F2, the cleavage is also 1: 1 by phenotype and genotype (furry: smooth-haired and Aa: aa, respectively).
