Answer:

1. BB x bb

2. 100% black

Explanation:

Heterozygous offspring would have the genotype Bb. In order to produce offpsring that are 100% heterozygous, that means each parent must be homozygous. Therefore, the genotypes of the parents are BB (black rabbit) and bb (white rabbit). See punnet square attached.

The phenotype refers to the expression and display of the genotype. We will assume that because black is denoted by a capital B, and white by a small b, that black is the dominant allele. Therefore, if 100% of the offspring have the genotype Bb, then 100% of the offspring have the phenotype of black fur.
