rabbits, white coat color (CW) and black coat color (CB) are codominant, and both alleles are dominant over albino (c); heterozygotes (CWCB) are spotted. Cross a heterozygous black-coated rabbit with a homozygous white-coated rabbit. What percent of the offspring will have black coats? Read the question carefully. Then enter your answer in the box provided

Answer (1)

Let's break down the genotypes and phenotypes:- CW: White coat- CB: Black coat- c: Albino- CWCB: Spotted (heterozygous)Given:- Parent 1 (Black-coated, heterozygous): CWCB- Parent 2 (White-coated, homozygous): CW CWPossible offspring genotypes and phenotypes:1. CW CW (White)2. CW CB (Spotted)Probability of each genotype:1. CW CW: 50% (homozygous white)2. CW CB: 50% (heterozygous, spotted)No offspring will be homozygous black (CB CB), so:- Percent of offspring with black coats: 0%The correct answer is: 0Note: The question asks for the percentage of offspring with black coats, not spotted coats. Spotted coats are heterozygous (CWCB), while black coats require the homozygous genotype CB CB, which is not possible in this cross.Carry on learning!
