Question

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

Explanation:

Step1: Set up Punnett - square

The parent genotypes are BB and WW. The possible gametes from the BB parent are all B, and from the WW parent are all W.

Step2: Fill in Punnett - square

When we fill in the Punnett - square, each box is the combination of a gamete from one parent with a gamete from the other parent. So, all the offspring genotypes are BW.

Answer:

The genotype of the offspring is BW. Since both black and white feathers are expressed in the offspring, this is an example of codominance.
