Detailed explanation-1: -Each variation of a gene is called an allele (pronounced ‘AL-eel’). These two copies of the gene contained in your chromosomes influence the way your cells work. The two alleles in a gene pair are inherited, one from each parent. Alleles interact with each other in different ways.
Detailed explanation-2: -Within an individual organism, the specific combination of alleles for a gene is known as the genotype of the organism, and (as mentioned above) the physical trait associated with that genotype is called the phenotype of the organism.
Detailed explanation-3: -Different versions of the same variant are called alleles. For example, a SNP may have two alternative bases, or alleles, C and T4. When working with genome scale data the term reference allele refers to the base that is found in the reference genome.
