3. If a red-eyed heterozygous fly (Rr) mates with a sepia-eyed homozygous fly (rr), what are the possible genotypes of their offspring? (Hint: You many want to complete a Punnett square.)

R r

r Rr rr

r Rr rr

Genotypes:

There is a 50% chance the offspring will be heterozygous (red-eyed) and a 50% chance the offspring will be homozygous recessive (sepia-eyed).
