Study Notes
Variations
- Variations refer to different characteristics within the same species.
Inherited Variations
- Inherited variations are traits passed down from parents through sexual reproduction.
Acquired Variations
- Acquired variations result from experiences and environmental factors throughout an individual's life.
Sources of Variation
- Key sources of variation include meiosis and sexual reproduction.
Mutations
- Mutations are alterations in DNA structure or quantity that can introduce new genes to a population, potentially leading to beneficial or harmful traits.
Mutagens
- Mutagens are agents or substances that trigger mutations in the genetic material.
Point Mutation
- A point mutation is a specific change in a gene, exemplified by conditions like sickle cell anemia.
Chromosome Mutation
- Chromosome mutations involve changes in the structure or number of chromosomes, as seen in disorders like Down syndrome.
Evolution
- Evolution is defined as the inheritable genetic change in a species over extended periods, driven by environmental changes.
Species
- A species is a collection of similar organisms that can reproduce and produce fertile offspring.
Theory of Evolution
- The theory of evolution was proposed by naturalists Charles Darwin and Alfred Wallace.
