A human population containing 200 individuals has two alleles at the 'T' locus, named T and t. T, which produces tall individuals, is dominant over t, which produces short individuals. If the population has 90 TT, 40 Tt and 70 tt genotypes, what will be the frequencies of these two alleles in this population?
