The history of the development of genetics as a fundamental science

General idea of ​​genetics as a science

Human genetics is the science of human heredity and variability.

Heredity is the ability of living organisms to preserve and pass on the signs and properties of an organism from generation to generation.

Variability is the ability of living organisms in the process of ontogenesis to lose old and acquire new signs and properties.

The main stages in the development of human genetics

1900 - the beginning of the rapid development of genetics as a science - the second discovery of Mendel's laws by three scientists independently from each other: de Frieze (Holland), Correns (Austria), Chermak (Germany).

G. Mendel discovered the patterns of inheritance of characters in 1865 and published in German in the writings of the society of natural scientists entitled "Experiments on Plant Hybrids."

1900 - 1930
- the classical period of the development of genetics (the stage of mendelism and the chromosome theory of heredity).

1930 - 1940 - the period of induced mutagenesis (obtaining mutations using radiation and chemicals).

1940-1953 - 2000 - the period of molecular genetics (study of the structure and functional nature of DNA molecules).

1953 - Watson and Crick transcribed the structure of a DNA molecule.

2000 - the human genetic code has been completely deciphered - it can be completely written down using chemical formulas.

after 2000 - the current stage - the main direction - structural and systemic knowledge of the deep essence of the gene.
