ABO Blood Group System - Blood Types and ABO Antigens

Explore the intricacies of the ABO Blood Group System in this comprehensive 47-minute lecture. Delve into the nature of A, B, AB, and O blood groups, understanding the role of H antigen as a precursor to RBC antigens. Learn about the transformation from H substance to A and B antigens, focusing on the crucial roles of N-Acetyl Galactosamine (NAGA) Transferase and B transferase. Examine the influence of maternal and paternal genes on blood group determination. Compare blood groups A and B in terms of heterozygosity and homozygosity, exploring their genotypes and phenotypes. Investigate the AB blood group's unique characteristics and the genetic factors behind the O blood group. Conclude with an in-depth look at the genetics of the ABO system, including transferase A, transferase B, non-functional gene variants, and the concepts of dominant and recessive alleles.
