Question

what are different versions or variants of a gene called

Answer 1

Different versions or variants of a gene are called **alleles**. Alleles can differ in their DNA sequence and can lead to variations in traits. For example, in humans, the gene for eye color has several alleles that can result in different eye colors such as brown, blue, or green. Additionally, when multiple alleles exist for a gene within a population, this situation is referred to as **allelic diversity**.
