Answer:

Rr, round wings

Step-by-step explanation:

The wings will all be Rr, which makes them all round. If round wings are the dominant trait, then they can be represented as either RR or Rr. But if pointy wings are recessive, they can only be represented as rr. Genotype is the genetic makeup of an organism, and can be represented as Rr (dominant), RR (dominant), and rr (recessive). The Phenotype is the visible traits, such as hair color, eye color, or in this case, wing type. recessive traits can only appear when there are two little r's: rr. So they genotype can be represented as Rr, and the phenotype can be represented as round wings.

I hope this helps and have a great day!
