Study Notes
Genetics
- Genetics is the branch of biology that studies genes, genetic variation, and heredity in organisms.
- The first scientist to study genetics scientifically was Gregor Mendel.
Gregor Mendel's Research
- Gregor Mendel studied the inheritance of traits in pea plants (Pisum sativum) in his research.
- He observed that traits are inherited in a predictable manner, and he used the term "factors" to describe the units of inheritance.
- Later, these "factors" were renamed as "genes".
Principles of Genetics
- The primary principles of genetics in the 21st century are based on Mendel's laws, including the law of segregation, the law of independent assortment, and the law of dominance.
Importance of Genetics
- Genetics is an important branch in biology because it helps us understand how traits are inherited, and how genetic variations can affect an organism's characteristics and health.
Levels of Genetics
- Genetics is studied at three levels:
- Molecular level (gene structure and function)
- Organismal level (genetic variation)
- Population level (distribution of genes in populations)
