MCQ (Single)Mendel's Experiments with Pea PlantsDominant and Recessive TraitsLaw of Independent Assortment

Mendel worked out the rules of heredity by working on garden pea using a number of visible contrasting characters. He conducted several experiments by making a cross with one or two pairs of contrasting characters of pea plant. On the basis of his observations he gave some interpretations which helped to study the mechanism of inheritance.
