Final answer:
When a trait develops from both genetic and environmental effects, it means that both factors play a role in influencing the expression of the trait.
Step-by-step explanation:
When a trait develops from both genetic and environmental effects, it means that both factors play a role in influencing the expression of the trait.
Genetic effects refer to the influence of an individual's genes or DNA on the development of the trait, while environmental effects refer to the impact of the individual's surroundings or external factors on the trait.
For example, height is a trait that is influenced by both genetic and environmental factors. While an individual's genes determine their potential height, factors like nutrition, exercise, and overall health can also impact their actual height.
Similarly, personality traits can be influenced by both genetic predispositions and the environment in which a person is raised.
Understanding the interplay between genetics and environment in trait development is important for gaining insights into human behavior, intelligence, and various other complex traits.
