The Cy allele causes curly wings in flies. Heterozygous flies have one wild type allele and one Cy allele. When two heterozygous flies are crossed, their offspring can have different combinations of alleles. The Punnett square for this cross would be: | C | y | |-----|-----| | C | CC | Cy | | y | Cy | yy | So, in the F₁ generation, we would expect to see wild type flies with the genotype CC or Cy, and curly wing flies with the genotype Cy. Thus, the correct answer is A, wild type and curly wings.
