Ou are given two true-breeding groups of rabbits. The first group has floppy ears and white fur. The second group has straight ears and black fur. When you perform a cross of these two groups to obtain a F1 generation you see that all of your rabbits have floppy ears and gray fur. If you knew that each of these traits was determined by a single gene and underwent independent assortment, then you expect to see that 75% of your F2 generation rabbits have ears and of your rabbits have black fur.

you expect to see that 75% of your F2 generation rabbits have floppy ears and 25% of your rabbits have black fur.

Explanation:

Available data:

Having this information we can infer that floppy years, expressed by F allele, might be dominant over straight ears, expressed by f allele. And that the fur color is affected by incomplete dominance, being B the allele expressing black color, b the allele expressing white color and Bb the genotype for grey color.

Incomplete dominance is a condition where neither of the alleles completely dominates over the other one. Descendents possess an intermediate phenotype between the two parental phenotypes and not the dominant one.
