Pangenesis Theory

(i)         Charles Darwin propounded pangenesis theory.

(ii)         According to this theory every cell, of animal body produces many minute particles known as pangenes or gemmules.

(iii)        These gemmules are discharged in the blood stream and are deposited in the reproductive organs. These reproductive cells contain these pangenes and a child develops as a result of blending of the pangenes from two parents.

(iv)        Thus the individual would represent the mixture of both of the parents. The prevailing view of heredity in premendelian era was a Blending Theory.
