Answer 1

An allele is a form of a gene. It is one of two or more alternative versions of a gene that arise by mutation and are found at the same position on a chromosome. Each allele determines a specific trait or characteristic that can be expressed in an organism. Additionally, alleles can be either dominant or recessive, with dominant alleles being expressed over recessive alleles when present.
