Detailed explanation-1: -An allele is one of two or more versions of DNA sequence (a single base or a segment of bases) at a given genomic location. An individual inherits two alleles, one from each parent, for any given genomic location where such variation exists. If the two alleles are the same, the individual is homozygous for that allele.

Detailed explanation-2: -allele, also called allelomorph, any one of two or more genes that may occur alternatively at a given site (locus) on a chromosome. Alleles may occur in pairs, or there may be multiple alleles affecting the expression (phenotype) of a particular trait.

Detailed explanation-3: -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-4: -Some genes have only one allele, such as those on the human male’s Y chromosome, and any deviation from that allele can be harmful, or even fatal, to the organism. Genotype. Refers broadly to the genetic makeup of an organism-its complete set of genes.
