A gene has two sets of DNA.
The answer is an allele.
A gene pair is called an allele. An allele is an alternative form of a gene that is located on a specific chromosome at a specific place.
That is called heterozygous or it is called a hybrid.
dominant
One gene from a pair is called an "allele." Alleles are variants of a gene that can result in different traits or characteristics. Each individual inherits two alleles for each gene, one from each parent, and these can be either the same (homozygous) or different (heterozygous).
A pair of genes that are identical are called alleles. Alleles are different forms of the same gene that occupy the same position on homologous chromosomes.

It's called law of independent assortment.
