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. A Punnett square is shown. The columns are labeled Upper B and Upper B. The rows are labeled Upper W and Upper W. Clockwise from upper left the boxes contain: 1, 2, 4, 3.
All of the offspring are going to have a heterozygous genotype (BW)
Explanation:
If you cross BB and WW your Punnett square will be 100% heterozygous with all 4 offspring having a BW genotype and a phenotype of black and white feathers.
