Study Notes
Genetic Terminology
- The complete set of genes within an organism's genome is called the genome.
- Each organism’s genome contains all the genetic information necessary for its development and functioning.
Traits and Heredity
- A non-inherited trait is typically a phenotypic character that develops in response to environmental factors rather than genetic inheritance, such as a tan from sun exposure.
- In contrast, inherited traits are passed down from parents to offspring through genetic material.
Genetic Molecules
- The molecule that encodes genetic information and is passed from one generation to the next is DNA (deoxyribonucleic acid).
- DNA carries the instructions for the growth, development, and functioning of living organisms.
Study of Heredity
- The study of heredity in biology is known as genetics.
- Genetics examines how traits are transmitted from parents to offspring and the role of genes in influencing various characteristics.
Evolution of Species
- Species evolve primarily due to natural selection, a process where organisms better adapted to their environment tend to survive and produce more offspring.
- Other factors influencing evolution include mutations, genetic drift, and gene flow.
