Deficiency in the skin and hair pigment melanin

Reference no: EM1389881

Question: Albinism is a rare genetically inherited trait that is only expressed in the phenotype of homozygous recessive individuals (aa). The most characteristic symptom is a marked deficiency in the skin and hair pigment melanin. This condition can occur among any human group as well as among other animal species. The human frequency of albinism in North America is only about 1 in 20,000. If we assume this gene is in HW equilibrium, what is the predicted frequency of heterozygous individuals?
