Q14 of 53 Page 32

Even if a character shows multiple allelism, an individual will only have two alleles for that character. Why?

Humans are diploid organisms and each person posses only two alleles. Hence even if a character is controlled by a gene of three alleles like:- the ABO blood group controlled by gene I with three alleles IA, IB, i in humans; an individual will only have two alleles for that gene to control blood sgroup, which could be a combination of these three alleles like IAIA, IBIB, IAIB, IAi, IBi, and ii.
