Question

Distinguish between monohybrid and dihybrid cross. 

Distinguish Between

Solution

Monohybrid cross Dihybrid cross

The cross in which only one pair of contrasting characters is involved is known as a monohybrid cross.
 
The cross in which only two pairs of contrasting characters are involved is known as a dihybrid cross. 
A monohybrid cross is useful in determining the dominance of genes. 

A dihybrid cross is useful in studying the assortment of the offspring.

 
example: a cross between a tall and dwarf plant.
example: a cross between a tall plant having a red flower and a dwarf plant having a white flower.
