Helrine "Allele" and give one example of a gene with alleles in humans.

## Step 1<br />The term "allele" refers to different versions of the same gene. Each individual inherits two alleles for each gene, one from each parent. These alleles can be the same (homozygous) or different (heterozygous).<br /><br />## Step 2<br />The question asks for an example of a gene with alleles in humans. One such example is the gene responsible for eye color. The most well-known alleles of this gene are OCA2, which is responsible for the variation in eye color among individuals.<br /><br />## Step 3<br />The OCA2 gene has two main alleles: the "brown" allele, which results in brown eyes, and the "blue" allele, which results in blue eyes. The brown allele is dominant, meaning that an individual only needs one copy of this allele to have brown eyes. The blue allele is recessive, meaning that an individual must have two copies of this allele to have blue eyes.
