Get the answer of: Who was the Father of Genetics ?
Genetics is the branch of biology which deals with heredity and variations among related organisms. Heredity means the tendency of animals to resemble their ancestors and relatives. We have accomplished remarkable improvements in domestic animals and cultivated plants through the application of genetic laws.
But what about ourselves? A famous physician and geneticist, Sir Francis Galton (1822-1911) concluded that man as well as other animals are subjected to evolutionary process.

It is well-known to the student of genetics that most of the human traits (mental, physical and also physiological) have definite hereditary components. As our understanding of the nature of genes and our control of gene activity increases, possibilities for improving the lot of man in his environment have become realities.
The science ‘Genetics’ was born in 1866; Gregor Johann Mendel (1822-1884) was the “Father of Genetics”. After birth, this science was developed so much during the past century that nowadays it is— as particle physics—one of the most important branches of modern science.
Apart from all development and progress in the field of “Genetics” it is to be remembered that all the central problems of genetics was resolved after the discovery—”DNA is the genetic material”, by J. D. Watson and F. H. C. Crick (1953).
Mendel considered a single gene to be responsible for a single trait but it is now known that many genes are involved in the production of some traits. It is the genes and not the traits that are inherited. Gene behaves as a separate unit, whereas traits may result from complex interactions involving many genes.
ADVERTISEMENTS:
Mendel considered that dominance is an inherent property of genes. But dominance has not been shown to be influenced by factors in the external, internal (hormonal) and genetic environment.
Thus Mendel’s view of dominance as a fundamental inherent property of the allele alone is no longer tenable for all cases. The inheritance, particularly in eukaryotes, however, has proved to be a much more complex phenomenon than actually indicated by Mendel.
