Answer:
Option-B
Explanation:
Heredity refers to the passing of the traits from the parents to the offsprings or generation and also known as inheritance and Genetic variation is the difference in the genetic material in population which leads to the formation of a variety of traits.
Since the variation in traits is determined by factors (Gregor Mendel) later called "genes" which are passed on to the offsprings, therefore, the branch of biology which studies the pattern of inheritance and variation is known as "Genetics". Gregor Mendel is known as the Father of Genetics.
Thus, Option-B is the correct answer.
