4 Laws of Behavioral Genetics Correct Answers 1.) all human
behavioral traits are heritable
2.) the effects of being raised in the same family is smaller than
the effects of genes
3.) a substantial portion of the variations between human
behavioral traits is not accounted for by the effects of genes or
family
4.) a typical behavioral trait is associated with many genetic
variants, each of which accounts for a small percentage of that
behavioral trait
