Blood Type Genetic Basis: In genetics, blood type gene has two alleles, each allele has genotype A, B or O. The A and B are dominant, and O is recessive.So allele A combined with allele O is type A. Similarly, BO is type B, AA is type A, BB is type B, OO is type O, and AB is type AB.f both parents have type A blood, then the alleles could be AA or AO, thus the allele A frequency is 75%, allele O frequency is 25% for both parents. So the chance of alleles OO is 25% Ã 25% = 6.25%, alleles AA is 75% Ã 75% = 56.25%, alleles AO is 75% Ã 25% = 18.75%, alleles OA is 25% Ã 75% = 18.75%.
1. Cystic Fibrosis. Cystic Fibrosis is one of the most widespread inherited genetic disorders. It most often affects Caucasians who are Ashkenazi Jews. It occurs only when both parents are carriers, which gives their children a 1 in 4 chance of contracting the disease.
