Question

In chickens, Black feathers (B) are dominant over white feathers (b). Complete the Punnett

Square for the following cross:
Mother: BB
Father: bb
What percentage of offspring will be Black?
What percentage of offspring will be White?

Answer 1

(attached Punnett square below)

100% of the offspring will have black feathers

0% of the offspring will have white feathers

Step-by-step explanation:

All the possible offspring have the genotype Bb, and since B (black) is dominant it will be the phenotype regardless of the presence of a b allele.

Therefore, all the offspring will be black (100%) and since none of the genotypes are bb there's no chance for white feathered chickens (0%)

hope this helps!
