What is monohybrid cross?

A monohybrid cross is a genetic cross between two organisms that differ in only one trait.

In this type of cross, the inheritance of a single characteristic is studied, such as plant height, flower color, or seed shape. It helps in understanding how dominant and recessive traits are passed from parents to offspring.

For example, when a tall pea plant (TT) is crossed with a short pea plant (tt), the study of only the height trait represents a monohybrid cross.

Gregor Mendel used monohybrid crosses in his pea plant experiments to develop the basic laws of inheritance.

This type of cross is important because it helps explain genotype ratios, phenotype ratios, and the expression of traits in future generations.
