Summary Introduction
To match: The given term trait with its description.
Introduction: Gregor Johann Mendel is known as “Father of modern genetics”. He was the first person to conduct experiments on seven characters of pea plant. Based on these experiments, he framed three laws of inheritance, namely “Law of dominance, “Law of segregation”, and “Law of independent assortment.
