he next several questions refer to the data given in this problem. You sample a population of leafhoppers and genotype 250 individuals at a polymorphic locus with two alleles. You obtain the following numbers: AA = 68 individuals Aa = 54 individuals aa = 128 individuals what is the expected frequency with the aa genotype if the population is in hardy weinberg equilibrium (you may round your answer to the nearest whole number) Which of the following statements is supported, based on the data? (Check all that apply) 1.) The population is in Hardy-Weinberg equilibrium. 2.) The population is not in Hardy-Weinberg equilibrium, and the cause may be inbreeding. 3.) The population is not in Hardy-Weinberg equilibrium, and the cause may be selection favoring heterozygotes. 4.) The population is not in Hardy-Weinberg equibrium, and the cause may be population structure (in other words, the population we sampled actually may actually consist of two or more subpopulations that are at least partially isolated from one another).
