Name _____________________________ AP Biology 13 of 18 Adapted by Kim B. Foglia • • ©2008HARDY-WEINBERG PROBLEMS10. In fruit flies, Drosophila melanogaster, the allele for normal-length wing is dominant over the allele for vestigial wings (vestigial wings are stubby little curl that cannot be used for flight). In a population of 1,000 individuals, 360 show the recessive phenotype. How many individuals would you expect to be homozygous dominantand how many would be heterozygousfor this trait? a. Choose the letters you will use to represent the alleles & genotypes:
c. Choose which Hardy-Weinberg formula you will primarily use: ___________________________________________________________________________ d. Solve. Neatly show work below. Write final answer in box. ANSWER

In a population of 500 individuals, 25% show the recessive phenotype. How many individuals would you expect to be homozygous dominantand how many would be heterozygousfor this trait? a.
