2. Genes and Traits
- Genome: Contains DNA; sequences of DNA called genes control traits in an individual.
- RNA: Responsible for coding, decoding, regulating, and performing other functions in a cell, influencing
the development of traits.
3. Definitions of Key Terms:

- Phenotype: The expressed traits in an individual, which can be influenced by multiple genes.

eyes vs. blue eyes).
5. Genetic Influence:

influence personality traits, but the role of the environment in shaping traits like aggression is debated.

childhood, influenced by:
- Nutrition: Essential for brain and physical development.
- Caregiving and Parenting: Stable environments contribute to healthy development.
