in a sample of n diploid organisms, the frequency of an allele is calculated as: group of answer choices twice the number of occurrences of the allele divided by the total number of individuals (n). the number of occurrences of the allele. the number of occurrences of the allele divided by the total number of individuals (n). the number of occurrences of the allele divided by the total number of alleles of that gene in the sample (2n).
