Introduction

- All living organisms give rise to new individuals (offspring) by a

process of reproduction.

- The offspring produced as a result is similar to their parent but not

identical i.e. they also show some differences.

- The mechanism of transmission of character is called Heredity or

Inheritance while the differences seen among individuals is called

variations

Accumulation of Variation during Reproduction

- The differences in the characters (or traits) among the parents and

their offspring, the offspring or the individuals of same specs is

called as variation.

- Some amount of variation is produced during asexual reproduction

while the number of successful variations are maximized by the

process of Sexual Reproduction.
