here is your answer
Monohybrid cross: A genetic cross between parents that differ in the alleles they possess for one particular gene, one parent having two dominant alleles and the other two recessives.
Dihybrid cross is a pranit cross between two different lines (varieties, strains) that differ in two observed traits.
In the Mendelian sense, between the alleles of both these loci there is a relationship of complete dominance - recessive.
or
Monohybrid cross is the study of inheritance of one pair of contrasting characters. Through monohybrid cross experiments, Mendel proposed the Laws of Dominance and Law of segregation. For example, Tall stemmed plants are crossed with short stemmed plants. A new ratio of 3:1 is formed in the F2 generation. 75% individuals are dominant and 25% are recessive individuals.
Dihybrid cross involves the simultaneous inheritance of two individual characters of the same organism. It is the experimentation of two characteristics with their four contrasting traits. For example, Round and Yellow are the two dominant characters, Wrinkled and Green are two recessive characters. Round yellow seed plants are crossed with wrinkled green seed plants in dihybrid inheritance.This produced new ratio of individuals 9:3:3:1. Through dihybrid inheritance, Mendel proposed a new law, Law of independent assortment. Other than dominant and recessive, new combinations are also found.
