Overview
Dihybrid crosses are a fundamental concept in genetics that allow scientists to study the inheritance of two traits simultaneously. By using a Punnett square, one can predict the genotypes and phenotypes of offspring based on the alleles contributed by each parent. The expected phenotypic ratio of 9...
