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
Answer
Explanation:
Step1: Set up Punnett - square cross
The cross is between BB (black - feathered chicken) and WW (white - feathered chicken). The possible gametes from the BB chicken are all B, and the possible gametes from the WW chicken are all W.
Step2: Fill in the Punnett - square
When we fill in the Punnett - square, we combine the gametes. In box 1, we combine B from one parent and W from the other parent to get BW. Similarly, in box 2, 3, and 4, combining the gametes gives BW.
Answer:
BW
