The S-s antigen system in humans is controlled by twoco-dominant alleles, S and s.In a group of 3146 individuals the following genotypic frequencieswere found: 188 SS,717 Ss, 2241 ss.A) Calculate the frequency of the S and s alleles.B) Test whether the genotypic frequencies conform to theHardy-Weinbergdistribution using the Chi-square test.C) A third allele is sometimes found at the S locus. The allele suis recessive toboth the S and s alleles, and can only be detected in thehomozygous state. If thefrequencies of the alleles S, s, and su are p, q, and rrespectively, what would be theexpected frequencies of the phenotypes S_, Ss, s_, susu? **Youranswers will beequations written in terms of p, q and r.
