Step 1: Understanding Mendel’s contributions.
Gregor Mendel is known as the father of genetics for his work on inheritance patterns using pea plants.
Step 2: Pea plant experiments.
Mendel conducted controlled hybridization experiments on pea plants to study inheritance of traits.
Step 3: Laws proposed by Mendel.
He proposed law of dominance, segregation, and independent assortment based on his experiments.
Step 4: Concept of linkage.
Linkage was discovered later by Bateson and Punnett, not by Mendel. It refers to genes inherited together on same chromosome.
Step 5: Evaluation of options.
Thus, statement about Mendel discovering linkage is incorrect.
Step 6: Final conclusion.
Therefore, option (3) is incorrect about Mendel.
