Detailed explanation-1: -A dihybrid cross describes a mating experiment between two organisms that are identically hybrid for two traits. A hybrid organism is one that is heterozygous, which means that is carries two different alleles at a particular genetic position, or locus.

Detailed explanation-2: -A monohybrid cross is one in which both parents are heterozygous (or a hybrid) for a single (mono) trait. The trait might be petal color in pea plants. When conducting crosses, the first generation is called P (or P0), the second generation is F1 (F is for filial), and the next generation is F2.

Detailed explanation-3: -A monohybrid test cross is the process by which you cross two organisms that are heterozygous for a given trait. In such a case, by the law of dominance and by using the Punnett square, you know that the proportion of the offspring produced will be 25% homozygous dominant, 50% heterozygous and 25% homozygous recessive.
