Question

What was the reason for the scientific community not accepting Mendel’s proposal?

(a) Mendel’s factors blended, but natural changes were somewhat discrete

(b) Mendel’s factors were discrete, but natural changes blended

(c) Mendel’s factors were discrete, and natural changes were also discrete

(d) Mendel’s factors blended and natural changes also blended

This question was addressed to me in quiz.

This is a very interesting question from Chromosomal Theory of Inheritance-1 in chapter Principles of Inheritance and Variation of Biology – Class 12

Answer 1

The correct option is (b) Mendel’s factors were discrete, but natural changes blended

The best I can explain: Mendel’s laws of inheritance were based on the assumptions of factors/genes being discrete. However, most of the changes observed in nature exhibited the blending of characters. This led to the unacceptance of Mendel’s studies.
