Detailed explanation-1: -"Allele” is the word that we use to describe the alternative form or versions of a gene. People inherit one allele for each autosomal gene from each parent, and we tend to lump the alleles into categories. Typically, we call them either normal or wild-type alleles, or abnormal, or mutant alleles.

Detailed explanation-2: -Alleles are different versions of a gene, which vary according to the nucleotide base present at a particular genome location. An individual’s combination of alleles is known as their genotype.

Detailed explanation-3: -An allele is a term coined to describe a specific copy of a gene. Genes, the DNA sequences controlling our traits, are usually found in two copies in eukaryotic genomes; each copy (allele) is inherited from one parent. Each allele occupies a specific region on the chromosome called a gene locus.

Detailed explanation-4: -The presence of two identical alleles at a particular gene locus. A homozygous genotype may include two normal alleles or two alleles that have the same variant.
