In cabbage butterfly's white wings are dominant to yellow wings if a butterfly is crossed what a ww butterfly, what are the possible genotypes and phenotypes of the offspring and the percent chance for each

50% Ww with white wings

50% ww with yellow wings

Explanation:

In cabbage butterflies, White wings are dominant to yellow wings. If a Ww butterfly is crossed with a ww butterfly, what are the possible genotypes and phenotypes of the offspring and the percent chance for each?

White wing allele is W, since it is dominant over yellow wing allele which is w.

Ww is crossed with ww:

Ww x ww = Ww, Ww, ww and ww

Genotype of offspring: 2 Ww (white wings) and 2 ww (yellow wings)

50% of the offspring will genotype Ww with white wings while the remaining 50% will have genotype ww with yellow wings.
