In rabbits, the gray color of the coat dominates over the white, and the shaggy coat over the smooth one. What offspring should be expected if a gray hairy rabbit heterozygous for the second allele was crossed with a white smooth-haired rabbit?
A is gray wool, a is white.
B – furry, b – smooth coat.
Genotype of the white-smooth-haired rabbit-father: aabb (that is, he is a recessive homozygote, since the traits of a white and smooth coat are recessive).
The genotype of the gray furry rabbit is AaBb, as it is said to be heterozygous for both alleles.
Our offspring are as follows: AaBb – 25% shaggy gray rabbits; aaBb – 25% white hairy rabbits; Aabb – 25% gray rabbits with smooth coat, aabb – 25% white smooth coat.
