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

Explanation

### Step-by-Step Text Solution:

1. **Understanding Multiple Alleles**:
- Multiple alleles refer to the existence of more than two forms of a gene that occupy the same locus on a chromosome. For example, the ABO blood group system in humans has three alleles: I^A, I^B, and i.

2. **Diploid Organisms**:
- Most organisms, including humans, are diploid, meaning they have two sets of chromosomes (2n). One set comes from the mother and the other from the father. Therefore, for any given gene, an individual can only inherit two alleles—one from each parent.
