An experimental cross where only a single character is considered (for example, flower color) is called: a cross or single factor cross.
A monohybrid mating is a mating between two organisms that have different variations at the genetic locus of interest. Traits examined in monohybrid matings are determined by two or more variations at a single locus of a gene. To perform such matings, each parent is selected to be homozygous or homozygous for a particular trait (locus).
If a cross meets the criteria for a monohybrid cross, it is usually established by a characteristic distribution of second-generation (F2) progeny, sometimes referred to as the monohybrid ratio.
Generally, monohybrid crosses are used to determine the dominance relationship between two alleles. The cross begins with the parental generation. One parent is homozygous for one allele and the other parent is homozygous for the other allele.
