Bryan has albinism, an autosomal recessive trait, which means he is homozygous recessive for albinism and his genotype is aa. Bryan's parents, Frank and Amy, do not have albinism however they must both be heterozygous. Bryan's sister, Allice, is a carrier for albinism. If Allice has offspring with Jim, who has no family history of albinism, what are the chances that their offspring are carriers for albinism? What are the chances that they children will get albinism? Use Punnett squares

Ans: Albainism is an autosomal recessive disorder. For this disease to develop two copies of an abnormal gene must be present. A normal person will have the genotype AA and a carrier person will have the genotype Aa.
It is disorder in which the human lost the partial or complete pigmentation of skin, hair, and eye. The absence of defect in tyrosine, a cooper containing enzyme that is involved in the production of melanin cause this disease.
