Answer 1

Answer:

An allele is a viable DNA (deoxyribonucleic acid) coding that occupies a given locus (position) on a chromosome. Usually alleles are sequences that code for a gene, but sometimes the term is used to refer to a non-gene sequence. ... An organism which has two different alleles of the gene is called heterozygous.
