Question

a chicken with black feathers (bb) is crossed with a chicken with white feathers (ww). the offspring have black and white feathers. 1. what is the genotype of the offspring? 2. 3. 4. this is because there are two traits.

Explanation:

Step1: Analyze the cross

When a chicken with black feathers (BB) is crossed with a chicken with white feathers (WW), each parent contributes one allele. The black - feathered chicken (BB) can only contribute a 'B' allele, and the white - feathered chicken (WW) can only contribute a 'W' allele.

Step2: Determine the genotype of offspring

Using the Punnett square method (where one parent's alleles are on the top and the other's on the side), for each box in the Punnett square:

• When \(B\) (from \(BB\)) combines with \(W\) (from \(WW\)), the genotype of the offspring is \(BW\) in all cases.

Answer:

All of the offspring have the genotype \(BW\)
