Explanation:

What is having two different genes for a trait?

In other cases, each parent provides a different allele of a given gene, and the offspring is referred to as heterozygous("hetero" meaning "different") for that allele.Alleles produce phenotypes (or physical versions of a trait) that are either dominant orrecessive.

There are usually at least two forms (called alleles) of most genes, and the effect theyhave when expressed in the individual, i.e. the characteristic they produce, varies according to the form of the other gene they arecombined with in each body cell. ... alleles show their effect only if both genes are of this type.

heterozygous
