What chromosomes are affected in Oculocutaneous albinism?
Inheritance OCA type 1 is caused by a gene on chromosome 11 and is inherited as an autosomal recessive trait, meaning the an individual must inherit two defective genes for the disorder to occur. OCA type 2 is caused by a gene on chromosome 15 and is also inherited as an autosomal recessive trait. OCA type 3 is caused by a gene on chromosome 9 and is also inherited in an autosomal recessive manner. Ocular albinism is caused by a gene on the X (female) chromosome. It is also a recessive disorder, meaning that a male inheriting one defective X chromosome will have ocular albinism, but a female would have to inherit two defective X chromosomes to have the disorder. Hope that helps! good luck on that bio pres.
