Understanding Inheritance and Variation
Heredity is the transmission of characters from parents to offspring. Evolution is the gradual change in the characteristics of a population over several generations, leading to the formation of new species.
Important Concepts for HSLC 2027
- Mendel's Laws: Law of Dominance, Law of Segregation, and Law of Independent Assortment.
- Sex Determination: How the sex of a human offspring is determined.
- Evolution: Natural selection, genetic drift, and the role of environment.
- Acquired and Inherited Traits: Difference between traits developed during life and those passed through genes.
- Speciation: Factors leading to the formation of new species.
- Evidence for Evolution: Homologous and analogous organs, and fossils.
