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%.
Autosomal recessive: cystic fibrosis (CF), sickle cell anemia (SC), Tay Sachs disease. Genes are inherited from our biological parents in specific ways. One of the basic patterns of inheritance of our genes is called autosomal recessive inheritance.utosomal recessive inheritance means that the gene is located on one of the autosomes (chromosome pairs 1 through 22). This means that males and females are equally affected.
