What is a Monohybrid Cross? Mendel's Experiment

What is a Monohybrid Cross? Mendel's Experiment

Monohybrid cross involves inheritance of one pair of contrasting characters, such as tall and dwarf characters or red and white flower color, etc.

The results of monohybrid cross in F2 generation are in 3 : 1 ratio.

Which of the following can be concluded from Gregor Mendel's experiments with pea plants?

Mendel cross-pollinated two varieties of Pisum sativum pure or homozygous for tall and dwarf (P1 generation) characters.

The seeds obtained as a result of cross-pollinated grew into tall progeny, and he named it first filial generation (F1).

Now he allowed the F1 plants to self pollinate. The offspring of this generation (i.e., second filial generation or F2) were both tall and dwarf in the ratio of 3:1.

O self-pollination, the dwarf plants of F2 were found to breed true to dwarfness in succeeding generations.
