Answer 1

The offspring have the genotype of BW
You can prove this by doing a Punnet Square
Hope this helps! :)

Answer 2

Answer: The genotype of the offspring is BW.

Explanation-

The offspring with black and white feathers is the case of co-dominance. This is because both the alleles ( 'B' for black feather and 'W' for white feather) are equally expressed in the offspring resulting in black and white feathers.

Thus, the genotype of the offspring with black and white feathers is BW.
