Monohybrid cross.
A monohybrid cross is a genetic cross between two individuals, who have homozygous genotypes, or genotypes that have completely dominant or completely recessive alleles, which result in opposite phenotypes for a certain genetic trait.
Monohybrid crosses are used by geneticists to observe how the offspring of homozygous individuals express the heterozygous genotypes they inherit from their parents. Typically, this cross determines the dominant genotype.
