Question

What term defines a gene made up of two different alleles

Answer 1

The right answer is Heterozygous

An individual is heterozygous for a gene when he has two different alleles of that gene.

Heterozygosity, being heterozygous, decreases the risk of expression of deleterious recessive alleles and allows for different versions of the same gene, which can be a guarantee of adaptability to changing environmental conditions.
