One fruit fly is heterozygous for long wings, and another fruit fly is homozygous for short wings. Long wings are dominant to short wings. Using a punnett square, find out what percent of the offspring are expected to have short wings.

Answer 1

Ll x ll gives Ll, Ll, ll, ll
short wings: half of the flies.

Answer 2

A biologist finds that 29% of fruit flies have short wings and 50% have eye defects. Assuming these two events are independent, what is the probability that a randomly selected fruit fly has neither short wings nor eye defects?
