In rabbits longhair is recessive to short hair If a homozygo

In rabbits longhair is recessive to short hair. If a homozygous short haired female is mated with a homozygous long-haired male, what are the expected phenotypes and genotypes of the first generation (F_1)? If the male is a heterozygote then what are the expected phenotypes and genotypes of the first generation (F_1)?

Solution

Cross between homozygous short haired female (ll) and homozygous long haired male (LL)

LL x ll

All the F1 plants are heterozygous short haired (as long hair is recessive to short hair)

Genotype -----Ll

Phenotype-----short hair

Cross between heterozygous male and homozygous female

Ll x ll

All F1 plants are short haired; 50% are homozygous short haired and 50% are heterozygous short haired.

Phenotype------ short haired

Genotype---- Ll and ll
