Study Notes
Genetic Basis of Behavior
- Behavior is influenced by a combination of genetics and learning.
- Researchers use various methods to determine the extent of genetic and environmental contributions.
- One method examines variation within a species.
- Five methods are used to test if behavior is genetic, learned, or a combination of both.
Variation Between Individuals
- Comparing individuals of the same species sheds light on the relative importance of genetic and environmental factors.
Studying Naïve Youngsters
- Studying newborn/naïve animals provides insights into innate behaviors.
- Coastal and land snakes (same species) display differing food preferences, suggesting a role for genetics.
- Experiments involving newborn snakes tested their preferences for slug-based foods.
- Newborn inland snakes generally showed a preference to not eat slug-based foods, (chunks of slug and swabs of slug mucus).
- This suggests a genetic predisposition towards specific food choices, influencing behavior.
- Very few baby inland snakes ate the slugs.
