Answer:
Parents & Gametes: Bb × bb
Genotype Ratio: 1Bb:1bb
Phenotype Ratio: 1black fur: 1white fur
Explanation:
This is a monohybrid cross involving a single gene coding for fur colour in rabbits. The allele for black fur (B) is dominant over the allele for white fur (b).
In a cross between heterozygous black male with a homozygous white female, a heterozygous black male will possess genotype: Bb while a homozygous white female will possess genotype: bb
Hence, using a punnet square, the following gametes will be produced by each parent as follows:
Bb- B and b
bb- b and b
The genotypic ratio based on the punnet square is 1Bb : 1bb
The phenotypic ratio is 1 black : 1 white fur rabbit
