| Heterozygous for both traits, a black, furry rabbit was crossed with a homozygous, white, smooth rabbit. Identify the hebrides of the offspring by phenotype and genotype.
The rabbit is heterozygous.
We denote the black color of the coat as A – the dominant feature,
a – white (recessive).
The female – furry – is the dominant feature, we denote V.
The male is homozygous for both traits: white – a (recessive), b – smooth.
Let’s draw up a solution scheme.
P ♀ AaBb x ♂aabb.
G AB, Ab, ab, ab ab.
F1 АаВb – black, hairy;
Aabb – black, smooth;
aaBb – white, hairy;
aabb – white, smooth.
Cleavage by phenotype and genotype 1: 1: 1: 1.
