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: -Alleles of a particular gene differ from each other genetically in their nucleotide sequences. As a result, their products and traits expressed could be different. Significance:Alleles add variability in the population.
Detailed explanation-4: -Since there are two copies of each gene, there are two alleles, which may be the same or different.
