00:24:27 Relation between genotype and phenotype with subsequent blood groups
00:30:41 Why AB blood group is called AB? Origination of its antigens along with role of H antigen
00:34:23 Antigens in blood group O and the reason why it is called blood group O?
00:37:26 Definition of allele, concept of dominant and recessive allele with examples and their relations with ABO blood group system

---------------------------------------------------------------------------------------------------------------------------

Nature of A, B, AB and O Blood Groups,
H antigen/H substance as precursors of RBC antigens,
From H substance to A antigen; Role of N-Acetyl Galactosamine (NAGA) Transferase/Transferase A
H substance to B antigen; Role of B transferase; role of maternal and paternal genes in contributing to blood groups

Further comparison of blood groups A and B in terms of being hetero- and homozygous for either A or B; genotypes and phenotypes for A or Blood gorups

AB blood group; genotype, phenotype

O blood group; non functional gene variants

Genetics of ABO system; transferase A, transferase B or non-functional gene variants and dominant and recessive alleles.
