In a given population of diploid individuals, two alleles of gene A exist, A and a. Gene A DNA from 100 individuals is amplified and the PCR products are sequenced to determine which allele(s) each individual has (their genotype). The results demonstrate that the sample is made up of 16 AA, 48 Aa, 36 aa individuals. 1. What is the number of A alleles in this sample? (Click to select) 2.
