Heredity = Transmission of genetic characters from parent to offsprings.
Variation = Individuals of the same species have some differences; this is called variations.
History of researches in genetics:
i)G.J. Mendel - Father of Genetics.
ii)W. Bateson - Father of Modern Genetics.
iii)Morgan - Father of Experimental genetics
He experimented on Drosophila & proposed various concepts, like Linkage, Sex linkage,
Crossing over, Crisscross inheritance, Linkage map on Drosophila.
iv)A. Garrod = Father of human genetics & Biochemical genetics. Garrod discovered the first human Metabolic genetic disorder which is called alkaptonuria(black urine disease )
