Genetics is the study of heredity and variation
Heredity is the transmission of characters from one generation to another
Variation refers to the differences among individuals in a population
Gregor John Mendel laid down the foundation of genetics and is called father of genetics.
He worked on the pea plant (Pisum sativum) and published his work in 1866
But his work remained unnoticed during his life time due to various reasons
His work was rediscovered during 1900 by 3 different scientists simultaneously
1. Hugo De Vries – a Dutch biologist
2. Carl Correns – a German botanist
3. Erich Von Tshermark – an Austrian botanist
