Answer:
The correct answer is - 1:2:1 for black : blue : white chicken.
Explanation:
We know that color of the feather is a trait of the chicken that shows the codominance type of inheritance pattern where both forms of the trait are dominant and make a mix of the forms. In this case, blue is heterozygous BW and black BB and white is WW, then crossed between BW with BW
gametes: B, W and B, W
Punnett
B W
B BB BW
W BW WW
thus, the phenotypic ration is - 1 black : 2 blue : 1 white
