6.) In fruit flies, yellow body is recessive to gray body. A
yellow bodied female mates with a gray bodied male. All the
male progeny have yellow bodies and all the female progeny
have gray bodies. The reciprocal cross yields male and
female progeny that have gray bodies. Based on this, yellow
is a (multiple choice)
