What is the proportion of different genotypes and phenotypes obtained in the following crosses in foxes?

a) Pure x heterozygous redhead

b) Heterozygous x black

c) Pure red x black

Answer:

In foxes, the proportion of different genotypes and phenotypes obtained in the given crosses can be determined. The genotypes and phenotypes vary depending on the specific crosses.

Explanation:

In foxes, black fur is due to the b allele and red fur to the B allele. Here are the proportions of different genotypes and phenotypes obtained in the given crosses:

a) Pure x heterozygous redhead:

Genotypes: 50% Bb and 50% BB

Phenotypes: 50% red and 50% black

b) Heterozygous x black:

Genotypes: 50% Bb and 50% bb

Phenotypes: 50% red and 50% black

c) Pure red x black:

Genotypes: 100% Bb

Phenotypes: 100% red
