Answer Details
A pair of genes that control a trait is referred to as "alleles" (as stated in).
An allele is a specific version of a gene, which determines a particular trait or characteristic. Each individual organism inherits two alleles for each gene, one from each parent, and the combination of these alleles determines the organism's phenotype, or observable traits.
In genetics, alleles can be dominant or recessive. A dominant allele is expressed when an individual has either one or two copies of the allele, while a recessive allele is only expressed when an individual has two copies of the allele.
A hybrid, on the other hand, refers to an offspring of two different species or varieties, or of genetically dissimilar parents. It is not a term that describes a pair of genes that control a trait.
Therefore, a pair of genes that control a trait is referred to as alleles, which can be dominant or recessive.
