Study Notes
Inheritance
- The principles of inheritance primarily focus on how traits are passed down from one generation to the next.
- This involves understanding the mechanisms of inheritance, including genes, chromosomes, and the processes of meiosis and fertilization.
Variation
- Variation in genetics refers to the differences in traits observed among individuals within a population.
- This variation arises from various sources, including genetic mutations, gene shuffling during sexual reproduction, and environmental influences.
Central Concepts
- The concept of natural selection is NOT central to the study of inheritance and variation.
- While natural selection acts upon variation to drive evolution, it's a separate concept from the mechanisms of inheritance and variation themselves.
Environmental Influence
- Environmental factors can influence variation by affecting gene expression.
- This can result in phenotypic differences even among individuals with the same genotype.
- For example, identical twins raised in different environments may show slight differences in certain traits.
Inheritance and Variation Relationship
- Inheritance provides the foundation for variation.
- It's the transmission of genetic information from one generation to the next that creates the potential for variations within a population.
- Variations are then subject to evolutionary pressures, such as natural selection.
