A researcher notes that male-female pairs of fraternal twinsshare a similar environment in a mothersâ womb. This exposes thefemale twin to higher levels of the hormone testosterone duringprenatal development. This hormone is thought to be responsible formasculinizing the brain (it leads to male-typical behaviors).Likewise, the male twin is exposed to higher levels of the hormoneestrogen. This hormone is thought to be responsible for feminizingthe brain (it leads to female-typical behaviors). To test whetherexposure to testosterone and estrogen may influence male and femaletypical behavior, the researcher selected a sample of female-malefraternal twins and compared them to identical twins of each gender(male, female). She measured tendencies toward aggression using anaggression assessment where higher scores indicated greateraggression (a male-typical trait). It was hypothesized that ifhormone exposure influenced behavior, then aggression scores willvary among the groups.
