a) A population has only two alleles, R and r, for a particular gene. The allele frequency of R is 20%. What are the frequencies of RR, Rr, and rr in the population. Show all your work.
a.1) A large population consists of 400 individual, of which 289 are homozygous dominant (MM) , 102 are heterozygous (Mm) and 9 are homozygous recessive (mm). Determine the allele frequencies of M and m.
