Question

angela has a black heterozygous male cat and a white female cat black is dominant and white is recessive what are the genotypic ratios of this cross

Answer 1

See below

Step-by-step explanation:

Since the coat color black is a dominant trait, it can be represented by capital B. White colored coat for the female cat is a recessive trait so we can represent it with a small case b.

male parent: Bb x female parent: bb

The genotypes of F1 as Bb:bb will come out in a 1:1 ratio. This means there is a 0.5 probability of each kitten from this litter to have a white or black coat color.
