Solution

The correct option is A
Segregation

The alleles of the monohybrid F₁ segregate and enter into gametes separately without blending. The F1 plants produce two types of gametes. Assuming that these gametes combine randomly, we could say that in the F2 generation, homozygous dominant, heterozygous dominant and homozygous recessive individuals are produced in a 1:2:1 ratio.
