Monohybrid cross is cross between two individuals with a different variation of a single trait or single characteristic. That is Mendel crossed pure tall plant with the pure dwarf plant, here he considered height as the trait.

Dihybrid cross is a cross between two individuals differing in two different contrasting pairs of characters. That is Mendel crossed seeds of pea plant considering two characteristics of color (yellow and green) and texture (smooth and wrinkled).
