Question

List out the branches of Genetics that are divided by the modern geneticists for the sake of convenience of study.

 

Answer 1

Branches of Genetics:

1. Microbial genetics-It deals with the genetics of micro organisms (viz., viruses, bacteria, unicellular plants and animals).
2. Mycogenetics-The genetics of fungi (Burnett, 1975).
3. Plant genetics-The genetics of plants.
4. Animal genetics-The genetics of animals.
5. Human genetics-The genetics of man.
6. Population genetics-The genetics of the different populations of animal and plant species.
7. Cytogenetics-It provides the cytological explanations of genetical principles
8. Biochemical genetics-It provides the biochemical explanations of various genetical phenomena.
9.Molecular genetics-It is a most modern branch of genetics and it interprets most genetical phenomena in the term of chemic molecules.
10. Clinical genetics-It applies genetical analysis in diagnosing various hereditary diseases in man and suggests the possible cures for them.
11. Developmental genetics-It applies genetical knowledge to
the developmental biology,
12. Radiation genetics-It deals with the genetical effects of radiations on the living organisms.
13. Quantitative or biometric genetics-It deals with the inheritance of quantitative traits such as body weight, mature plant height, egg or milk production records, yield of grain per acre, etc.
14. Ecological genetics-It deals with the genetics of ecological phenomena.

Branches of Genetics:

For the sake of convenience of study, the modern geneticists have divided the science of genetics into following branches: microbial genetics, mycogenetics, plant genetics, animal genetics, human genetics, population genetics, cytogenetics, biochemical genetics, molecular genetics, clinical genetics, developmental genetics, radition genetics, quantitative or biometric genetics and ecological genetics.
