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. 2. 3. 4. done

Explanation:

Step1: Determine the gametes of each parent

The black - feathered chicken (BB) can only produce gametes with the allele \(B\). The white - feathered chicken (WW) can only produce gametes with the allele \(W\).

Step2: Use a Punnett square

When we cross \(BB\) (parent 1) and \(WW\) (parent 2), in a Punnett square, each cell will be the combination of one gamete from each parent. The cross is \(B\times W\) for each combination. So, all offspring will have the genotype \(BW\).

Answer:

All offspring have the genotype \(BW\)
