Give the meaning of the term allele.

Explanation

### Step-by-Step Text Solution:

1. **Definition of Allele**: An allele is defined as one of the alternative forms of a gene that can occur at a specific locus on a chromosome.

2. **Gene Representation**: Each gene can have different forms, known as alleles. For example, consider a gene that determines plant height. This gene can have two alleles: one for tall plants and another for short plants.

3. **Example of Alleles**: In the case of height, we can represent the tall allele as "T" (dominant) and the short allele as "t" (recessive).
