A person’s intelligence has been shown to have links to many genes that they inherit from their parents. In fact identical twins tend to have similar IQ’s. However, studies have shown that factors such as nutrition and family environment can contribute to the IQ a person has. What causes a person's intelligence?
Genetics only
Environment only
Neither
Both
What is the difference between inherited and environmental traits?
Environmental traits are learned from your parents and inherited traits are learned from the environment.
Environmental traits are acquired and inherited traits are learned.
Inherited traits come from your parents and environmental traits are learned behaviors.
Inherited traits come from your uncle and environmental come from the things around you.

Height is determined only by the genes inherited from parents.
Neither genes nor environment have any significant impact on height.

In an experiment, identical twins are raised in different environments. What is this experiment likely testing?
The influence of environment on genetic traits.
The influence of genetics on environmental traits.
The impact of identical environments on different genetic makeups.
The effect of random genetic mutations.
