Direct link to amanning08's post why All five of the above, Posted 3 years ago. The alleles help identify the amount of homozygous recessive or dominants,and the heterozygous dominants, which is basically enough to know the total alleles of a population. The eflects of natural selection are more pronounced In small populations. b. alleles of the gene pair are identical. In the article there is the statement: "Non-random mating won't make allele frequencies in the population change by itself, though it can alter genotype frequencies." 1. trends. 1 Thus the frequency of "r" in this secondpopulation is 0.1 and the frequency of the "R" allele is 1 - q or 0.9. Q6. c) either have the dominant or the recessive allele.
