Quizplus · Accepted Answer

A monohybrid cross involves the study of one trait while a dihybrid cross involves the study of two different traits. In a monohybrid cross, the organisms are heterozygous for only one character being studied, whereas in a dihybrid cross, the organisms are heterozygous for two characters that are being studied. The other statements are incorrect, as both types of crosses can involve one or two parents, and the ratios are different between the two types of crosses.
