Detailed explanation-1: -The correct option is A alleles. Alternative forms of a gene which occupy the same position on a chromosome are called alleles.

Detailed explanation-2: -"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-3: -Homologous chromosomes have the same genes arranged in the same order, but they have slightly different DNA sequences. Different versions of the same gene are called alleles (uh-LEELZ); homologous chromosomes often contain different alleles.

Detailed explanation-4: -Final answer: The term for alternative forms of a gene is known as allele or alleles.

Detailed explanation-5: -Explained in greater detail, each gene resides at a specific locus (location on a chromosome) in two copies, one copy of the gene inherited from each parent. The copies, however, are not necessarily the same. When the copies of a gene differ from each other, they are known as alleles.
