Genome BOW 5: Disease

Chromosome 9 is a well known gene that determines ABO blood type. The universal ABO system includes A, B, AB, and O which was discovered by Viennese. Type A can donate to A and AB, type B can donate to B and AB, type AB can only donate to AB, and O can donate to any blood types. The difference between blood A and B is 7 letters out of the 1062. The difference between type a and b from o blood type is that they are the same but o has deletion of letters. It is shown that O blood types are more affected to chloera but resistant to malaria. Type A, B, and AB are resistant to cholera and are affected to malaria. Cystic fibrosis is a gene on chromosome 7, it is a dangerous disease in the lungs and intestines but also protects the body from typhoid intestinal disease. An experience was made which resulted with choosing mates based on genes to prevent disease; Four men and women wears a cotton shirt for 2 night with no scent and 121 men and women will sniff and rate it from best to worst. It resulted with men and women both prefer body odor of the opposite sex who are genetically different from then genetically.
