Which among the following statement is incorrect regarding the experiment on garden pea Pisum sativum by Gregor Mendel ?

His experiments had a small sampling size, which gave smaller credibility to the data that he collected .

The correct answer is Option (3) – His experiments had a small sampling size, which gave smaller credibility to the data that he collected .

Gregor Mendel, conducted hybridisation experiments on garden peas for seven years (1856-1863) and proposed the laws of inheritance in living organisms. During Mendel’s investigations into inheritance patterns it was for the first time that statistical analysis and mathematical logic were applied to problems in biology. His experiments had a large sampling size, which gave greater credibility to the data that he collected.

Mendel investigated characters in the garden pea plant that were manifested as two opposing traits, e.g., tall or dwarf plants, yellow or green seeds. This allowed him to set up a basic framework of rules governing inheritance, which was expanded on by later scientists to account for all the diverse natural observations and the complexity inherent in them.
