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: -Final answer: The term for alternative forms of a gene is known as allele or alleles.
Detailed explanation-3: -Alleles are the alternative forms of a gene for producing different effects. The homologous individual contains two alleles which are the same for that gene. Heterozygous individuals contain the elements which are different for that gene. Alleles are usually used to describe the variation among genes.
