1. In Drosophila the allele for normal-length wings is dominant over the allele for vestigial wings (vestigial wings are stubby little curls that cannot be used for flight). In a population of 500 individuals, 180 show the recessive phenotype. How many individuals would you expect to be homozygous dominant and heterozygous for this trait?

The allele for unattached earlobes is dominant over the allele for attached earlobes. In a population of 1000 individuals, 25% show the recessive phenotype. How many individuals would you expect to be homozygous dominant and heterozygous for this trait?
