Human and, in fact, every animal or plant contains many gene oriented traits. This means that the traits depend on chromosomes and are mainly directed by DNA sequence. On the other hand, a particular trait of any species may have much discriminations. Generally, it is known that for dihybrid problem in generation F2, the phenotype ratio is 9:3:3:1 and the genotype ratio is 1:2:2:4:1:2:1:2:1. Here we consider a mathematical model on dihybrid as well as on multihybrid and analyise the probabilities of phenotype or genotype dissimilarities amongst them. Also the cause of it is shown graphically for dyhybrid.
