Answer:
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.
