A cross that examines a single trait is known as what?

Explanation:
Monohybrid cross focuses on one trait at a single gene locus. When you cross organisms that differ for only one characteristic, you’re watching how that single pair of alleles segregates and combines in the offspring, which is the essence of studying a single trait. For a typical monohybrid cross between heterozygotes, you expect the offspring to show a 3:1 ratio of the dominant to recessive phenotype, reflecting how the two alleles assort during gamete formation. The other terms describe different ideas: a dihybrid cross examines two traits at once, a pedigree charts inheritance across generations in a family, and “genotype cross” isn’t a standard label for a single-trait cross.
