Question

For B = black fur, b = white fur: Cross BB with Bb; which is the accurate phenotype ratio:

Answer 1

The phenotype ratio resulting from a cross between BB and Bb will be 100% black fur, as black fur is the dominant trait.

Step-by-step explanation:

When you cross BB (homozygous dominant for black fur) with Bb (heterozygous for black fur), you end up with the following genotype possibilities: BB, BB, Bb, and Bb. Considering black fur is the dominant trait, all of the offspring will display the black fur phenotype. Therefore, the phenotype ratio for this cross will be 100% black fur.
