Identify the incorrect statement regarding experiments on Pisum sativum by Gregor Mendel:
| 1. | He conducted hybridisation experiments on garden peas for seven years (1856-1863) and proposed the laws of inheritance in living organisms. |
| 2. | It was for the first time that statistical analysis and mathematical logic were applied to problems in biology. |
| 3. | Unfortunately his experiments had a small sampling size, which gave less credibility to the data that he collected. |
| 4. | He investigated characters in the garden pea plant that were manifested as two opposing traits. |
