Question

In butterflies, black wings are dominant over yellow wings. Use the Punnett Square to determine the possible genotypes and phenotypes if you cross two heterozygous butterflies. Use the letter B for your alleles.

Answer 1

The genotypes are one BB, two Bb, and one bb and the phenotype is three black and one yellow wing butterfly.

What are the genotype and phenotypes of the offspring?

The genotype and phenotypes of the offspring are determined using a Punnett square as follows:

Let B be black wing and b be yellow wings.

The cross between two heterozygous butterflies is:

• Bb × Bb = BB, Bb,Bb, bb

Black is dominant over yellow wings.

Therefore, the genotypes are one BB, two Bb, and one bb and the phenotype is three black and one yellow wing butterfly.
