Answer to Question #337645 in Genetics for freya

Question

For a human blood, there are two alleles (called S and s) and three distinct phenotypes that can be identified by means of the appropriate reagents. The following data was taken from people in Britain.

Among the 1000 people sampled, the following genotype frequencies were observed SS = 93, Ss = 420 and ss = 487.

Calculate the frequency of S and s in this population and carry out a chi- square test.

Is there any reason to reject the hypothesis of Hardy-Weinberg proportions in this population?
