1. A monohybrid cross is a cross between two organisms with different variations at one genetic chromosome of interest. The character being studied in a monohybrid cross are governed by two or multiple variations for a single locus.
2. A dihybrid cross describes a mating experiment between two organisms that are identically hybrid for two traits. A hybrid organism is one that is heterozygous, which means that is carries two different alleles at a particular genetic position, or locus.

A monohybrid cross involves a single parent, whereas a dihybrid cross involves two parents. A monohybrid cross produces a single progeny, whereas a dihybrid cross produces two progeny.
