Mendel proposed that the factor controlling any character is discrete and independent. This proposition was based on which of the following observations?

Easy

A

Offsprings of F₃ generation of a cross made between the plants having two contrasting characters show blended characters of its parents
B

Offsprings of a cross made between the plants having two contrasting characters shows only one character without any blending
C

Offsprings of self-pollination of F₁ parents with the same contrasting characters show blended characters of its parents.
D

Offsprings of cross-pollination of parental generations having three contrasting characters show only one character with belonging.

Solution

Characters are controlled by discrete units called factors. This was proposed by Mendel as only one of the parental characters in a monohybrid cross in the F₁and the expression of both in the F₂. The alleles do not show any blending and that both the characters are recovered as such in the F₂ generation though one of these is not seen at the F₁ stage.
