A homozygous dominant guinea pig with black fur is crossed with a homozygous guinea pig with white fur. the f1 generation is crossed with itself. what percentage of f2 generation is expected to show white fur coat?

Question: A homozygous dominant guinea pig with black fur is crossed with a homozygous guinea pig with white fur. the f1 generation is crossed with itself. what percentage of f2 generation is expected to show white fur coat?

The expected percentage of the F2 generation that will show a white fur coat is 25%. This is because the white fur coat is a recessive trait (bb), and in order to produce an individual with a white fur coat, both parents must pass a recessive allele to their offspring. When the F1 generation (which is heterozygous for fur color; Bb) is crossed with itself, each F2 offspring has a 25% chance of inheriting two recessive alleles (bb) from their parents and therefore displaying the white fur coat.
