Answer:
allele
Explanation:
An allele is an alternative form of a gene (in diploids, one member of a pair) that is located at a specific position on a specific chromosome.
Diploid organisms, for example, humans, have paired homologous chromosomes in their somatic cells, and these contain two copies of each gene.
An organism in which the two copies of the gene are identical — that is, have the same allele — is called homozygous for that gene.
An organism which has two different alleles of the gene is called heterozygous.
