Answer:
- Genotypes: 50% (Ww) and 50% (ww)
- Phenotypes: 50% will have white wings, and the other 50% will have yellow wings.
- Percent chance: 50% (heterozygous - Ww - yellow) and 50% (homozygous recessive - ww - white)
Explanation:
To answer this question, we make a Punnett square which looks like this:
You cross a heterozygous butterfly (Ww) and a homozygous recessive butterfly (ww), and it gives you:
Ww ww
Ww ww
As you can see from this Punnett square, 2 out of 4 have Ww, which makes it heterozygous and since they have the dominant W trait on them, they result to have white wings. The other 2 have yellow wings, since they have only w on them (recessive trait). Calculate percentages, you get 50% Ww and 50% ww.
