Question

1. which of the following represents the possible genotype(s) resulting from a cross between an individual homozygous for black fur (bb) and a heterozygous individual (bb)? a. bb and bb b. bb, bb, and bb c. bb only d. bb only e. bb only

Explanation:

Use a Punnett - square. The homozygous individual (BB) can only pass on the B allele, and the heterozygous individual (Bb) can pass on either B or b. So the possible genotypes of the offspring are BB (from B from the homozygous and B from the heterozygous) and Bb (from B from the homozygous and b from the heterozygous).

Answer:

A. BB and Bb
