Question
Human blood group is a good example of multiple allelism and co-dominance. Justify.
✓
Answer
Multiple allelism: Generally in an individual/population, only two alleles of a trait govern the character, but in case of ABO blood group, three alleles IA, IB and i are found to govern blood group in human population.
Co-dominance: Allele IA and IB when present in an individual, both being dominant express their own types of sugars/traits.
