Describe the mechanism of pattern of inheritance of ABO blood groups in humans. |
|
Answer» Human blood group is determined by glycoprotein/ antigen A and glycoprotein/ antigen B The alleles are `I^A,I^B`. Hence referred to as multiple allelism The individual inherits any two of them as given below `I^A,I^A" "Agroup ` `i^BI^B, I^Bi" " B group ` `I^AI^B" "AB group ` `ii " " O group ` In the case of A, B and 0 groups, Law of dominanee is the pattern tifinheritance as `I^A "and" I^B` are dominant over i. In AB group both the alleles `I^A "and " I^B` express themselves. Thus, it is the case of co-dominance. |
