Ccording to the Punnett square for this cross, what percentage of offspring is predicted to have blue feathers?

barxatty [35]

According to the Punnett square for this cross, 50% of offspring is predicted to have blue feathers. This is because the trait of a blue feather is dominant over the trait of a white feather. Thus, the correct option is B.

<h3>What is Punnett Square?</h3>

Punnett square may be defined as a kind of table in which all of the probable products for a genetic cross between two individuals with known genotypes are presented in a precise manner.

The complete question is described in the image given below:

When a Parakeet that is heterozygous (Bb) for blue feather (dominant) is crossed with a Parakeet that is purebred (bb) for white feather (recessive), the genotypes of the resultant offspring are Bb, bb, Bb, and bb.

In which 50% of the offspring possess blue feathers (Bb) while 50% of the offspring possess white feathers (bb).

Therefore, the correct for this question is B.
