Document Summary
Lecture 4: evolutionary change some examples of genetic markers. Some basic of blood types and abo distribution. Molecular genetic markers: blood type incompatibility: hemolytic disease of the newborn. There are at least 60 blood groups that are polymorphic. There are some blood types that are considered to be private and restricted to a family or small group of individuals, therefore useful for human genetics. Gene loci closely linked on 4th chromosomes. Two co-dominant genes for presence of antigen. Natural selection in malaria prevalent areas: fy4 antigen does not have attachment for vivax. Est. degree of admixture of european and african descent. Comment [ag1]: rh +/- determines fetus" rh; and if mother"s body can attack the fetus. Comment [ag2]: this is why when doing blood transfusion, we are not worried about your mn blood type. Can not create ab or h antigens, therefore you cannot have blood type a, b, or o. Commonly found in mohorati speakers in and around bombay.
