43. Consider the following scenario: A group of psychologists are studying the genetic influence on intelligence. They find that identical twins (raised together) have a heritability coefficient of .88 and that fraternal twins (raised together) have a heritability coefficient of 42. Based solely on these findings, the psychologists can legitimately conclude that A) intelligence is entirely shaped by genetics B) intelligence is entirely shaped by the environment C) intelligence is impacted be genetics D) intelligence is not impacted by the environment E) intelligence is not at all impacted by genetics
