Option 2 - Heredity


Heredity is a process by which an offspring cell or organism acquires characteristics of parent cell or organism. In more generic sense, it is referred to as passing on "traits" from parents to organisms. Gregor Mendel derived the basic concepts of heredity, which became a foundation for research and development in the field of genetics.

Incorrect Options

Option 1 – Differentiation: In biological terms, differentiation refers to cellular differentiation. Cells are organized into tissues, which perform specific physiological function. Differentiation is a process in which a less specialized becomes more specialized cell.

Option 3 – Immunity: Immunity is a state that describes presence of sufficient biological defenses to prevent infection, disease or other biological invasion.

Option 4 – Evolution: Evolution is change in genetic material from one generation to other. There can be small changes from one generation to other, which substantially accumulate over time causing substantial change in organisms.
