A pure-breeding fruit fly with curled wings mates with a pure-breeding fruit fly with normal (straight) wings. The F1 mate with each other to produce an F2 generation that consists of 160 flies with curled wings and 80 with straight wings. What can you infer from this observation?
A) Curled wings is a recessive trait. B) The dominant curled wing allele is also a recessive lethal. C) Wing shape is controlled by two codominant alleles. D) Two interacting genes determine wing shape. E) All of the hybrid F1 flies had straight wings.
