Study Notes
Genetics Subfields
- Transmission genetics deals with the inheritance of traits from one generation to the next.
- The area of genetics that focuses on the chromosomal basis of sex determination is cytogenetics.
Molecular Genetics
- Molecular genetics focuses on the structure and function of genes at the molecular level.
Applied Genetics
- Genetic engineering, an area of applied genetics, focuses on the repair of defective genes.
Historical Figures
- Friedrich Miescher is credited with identifying DNA (Nuclein) in 1869.
- Thomas Hunt Morgan and his colleagues conducted experiments on Drosophila (fruit flies) and discovered the phenomenon of crossing over.
- William Bateson coined the word 'genetics' in 1905.
Notable Discoveries
- Barbara McClintock and Harriet Creighton showed that genetic recombination is caused by a physical exchange of chromosomal pieces in corn.
Historical Theories
- Charles Darwin proposed the theory of Pangenesis, suggesting that each part of the body produces minute particles called 'gemmules' or 'pangenes'.
Eugenics Movement
- The eugenics movement became popular in the 20th century, fueling racist sentiment and leading to involuntary sterilization laws.
