What is the difference between monohybird cross and a dihybird cross?

A monohybrid cross involves the breeding of two organisms that differ in a single trait, focusing on the inheritance of one gene with two alleles. In contrast, a dihybrid cross examines the inheritance of two different traits, each governed by their own genes, typically involving four alleles. Monohybrid crosses yield a phenotypic ratio of 3:1 in the offspring, while dihybrid crosses typically result in a phenotypic ratio of 9:3:3:1. These crosses help illustrate Mendelian inheritance patterns in genetics.
