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 average human frequency of albinism in North America is only about 5 in 100,000. What are the allelic frequencies of a and A in the North American population if this population is in Hardy-Weinberg equilibrium? What are the frequencies of each of the three possible genotypes in the North American population if this population is in Hardy-Weinberg equilibrium?

Inheritance and Mendelian Genetics

Inheritance means the passing of traits to offspring from parents. These traits could be passed either through asexual reproduction or sexual reproduction. The offspring receives the genetic material from the parents. Mendelian inheritance is a certain biological inheritance that follows the rules and principles laid down by Gregor Mendel in 1865. The initial hypothesis was considered wrong, but other inheritance theories modified the concept of inheritance and thus genetics.
