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: -In contrast, the alternative allele refers to any base, other than the reference, that is found at that locus. The alternative allele is not necessarily the minor allele and it may, or may not, be linked to a phenotype. There can be more than one alternative allele per variant.
Detailed explanation-3: -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-4: -An allele is a variant form of a gene. Some genes have a variety of different forms, which are located at the same position, or genetic locus, on a chromosome. Humans are called diploid organisms because they have two alleles at each genetic locus, with one allele inherited from each parent.
Detailed explanation-5: -Final answer: The term for alternative forms of a gene is known as allele or alleles.
