Key Concepts Covered
➡️ Genetic variation – the diversity in DNA sequences among individuals in a species caused by mutations, sexual reproduction, and other factors.
➡️ Environmental influence – how external factors such as temperature, light, and nutrition can modify the expression of traits.
➡️ Mutations – changes in DNA that can create new traits, sometimes beneficial or harmful.
➡️ Gene flow and genetic drift – mechanisms that change the distribution of genetic traits within populations.
➡️ Phenotypic plasticity – the ability of an organism to alter its traits in response to environmental conditions.
