4. the study of 150 diploid individuals for a gene with 2 alleles (a and a) shows the following absolute genotype frequencies: aa: 0.15 aa: 0.44 aa: 0.41 a) [1 pts] calculate the allele frequencies. b) [5 pts] calculate the expected genotype frequencies under hw equilibrium. use the chi- square test to determine whether the observed and genotypes frequencies are significantly different. what will the allele frequencies be in the next generation?
