What this suggest about rounded wings?

The round wings of fruit flies is dominant over the curled type.

Explanation:

A dominant trait can be described as a trait which is determined by the dominant alleles. The dominant alleles have the tendency to mask the effect of the recessive trait. Hence, a dominant trait can either be homozygous or heterozygous for the trait.

A recessive trait gets suppressed y the dominant trait. For a recessive trait to occur, both the alleles of the gene should be recessive for that trait.

this is true, assuming that the allele is completely recessive and incomplete dominance is not a factor.
