What type of organism is produced when both parents are homozygous for different alleles at two genes of interest?

In the context of genetics, when both parents are homozygous for different alleles at two genes, the resulting organism is classified as a dihybrid. A dihybrid cross examines the inheritance of two different traits, with each trait being determined by two alleles—one from each parent. Here, "homozygous for different alleles" means that each parent has two identical alleles, but these alleles differ from one another for both genes.

This setup leads to offspring that can exhibit a combination of traits from both parents. For example, if one parent is homozygous for the dominant alleles of both genes (AA BB) and the other is homozygous for the recessive alleles (aa bb), the offspring will be dihybrid heterozygotes (Aa Bb). This results in a wider variety of potential combinations of traits in the offspring, demonstrating the principle of independent assortment and the resulting genotypic and phenotypic diversities that arise from such crosses.

The other options do not accurately describe this specific scenario. A monohybrid would refer to a cross involving only one gene, while being homozygous simply describes the genetic makeup of the parents without considering the traits being expressed. Poly
