Question

In humans, albinism is caused by loss of function mutations in genes involved in the synthesis of melanin, the dark pigment in skin. Only people homozygous for loss-of-function allege (genotype aa) have the albino phenotype. In Americans of northern European ancestry., albino individuals are present at a frequency of about 1 in 10,000 (or 0.0001). Assuming that genotypes are in Hardy-Weinberg equilibrium, what is the predicted frequency of Caucasians in the United States who carry a single allele for albinism

Answer 1

Answer: Approximately 1 in 70 individuals carry an mutated allele
