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

Options:

Answer:
B
Solution:

When Mendel crossed parents with two contrasting characters and observed in theF1generation, that only one character was expressed (the dominant one). On selfing theF1generation, the character which did not appear inF1generation appeared in theF2generation. This showed that there is no blending in the contrasting characters but they are discrete and independent. On the basis of this observation, Mendel proposed that the factor controlling any character is discrete and independent.
