Question
Monohybrid cross and Dihybrid cross.
| Monohybrid cross | Dihybrid cross |
| $1.$ Crosses involving a single pair of alleles are called monohybrid crosses. | $1.$ Crosses involving two pairs of alleles are called dihybrid crosses. |
| $2.$ Monohybrid crosses yield a phenotypic ratio of $3 : 1$ in the $F_2$ generation. | $2.$ Dihybrid crosses yield a $9 : 3 : 3 : 1$ ratio in $F_2$ generation. |
| $3.$ Monohybrid crosses yield $1 : 2 : 1$ genotypic ratio in $F_2$ generation. | $3.$ Dihybrid crosses yield $1 : 1 : 2 : 2 : 4 : 2 : 2 : 1 : 1$ genotypic ratio in $F_2$ generation. |
| $4.$ Application of the law of independent assortment is not applicable in monohybrid crosses. | $4.$ Application of the law of independent assortment is applicable in dihybrid crosses. |
