HEREDITY
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
Variation
- 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.
