Question

PLEASE ANSWER ASAP FOR BRAINESLT!!!!!!!!!!!!!!!!!!

Answer 1

Answer:

Genotypes Ww and ww, Phenotypes 50% white, 50% yellow

Explanation:

This question involves a single gene coding for wing color in cabbage butterflies. The allele for white wings (W) is dominant over the allele for yellow wings (w). This means that a heterozygous (Ww) will have the white color of wing.

According to this question, if a Ww (white) butterfly is crossed with a ww (yellow) butterfly, the following gametes will be produced by each parent:

Ww - W and w

ww - w and w

Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:

Ww, Ww, ww, we

Ww = white wings (50%)

ww = yellow wings (50%)
