Natural Selection Depends on Genetic Variation
... Example: A fruit fly population has a gene with two alleles A1 and A2. Tests show that 70% of the gametes produced in the population contain the A1 allele. If the population is in Hardy-Weinberg Equilibrium, what proportion of the flies carry both the A1 and the A1 alleles? ◦ What is given? p or q ...
