What are the general findings of identical twins separated at birth?
Identical twins separated at birth are not only in looks, they similar in behaviors throughout life, good or bad grades, use or non-use of alcohol, use or nonuse of illegal drugs, and type of family they get as adults. The text states that studies "clearly show that MZ (monozygotic) twins were far more similar in the traits of criminality." (Schram, & Tibbetts, 2014, p. 112)
What implications do these findings have for the importance of genetics or heritability regarding criminal behavior?
Genetics are a factor from the start with twins, identical twins are basically the same person, they are the only siblings known to have 100% identical DNA structure. "Ultimately, nature or biological factors tend to have an impact on behavior, often far more than the nurturing or environmental factors" (Schram, Tibbetts, 2014, p.132) The text also describes that studies have shown the best predictor to family members becoming or not becoming criminals is the mother's past criminality.

Studies of women who have been incarcerated showed that a large number of women have higher progesterone than estrogen. Medical studies show that this hormone imbalance takes place most often during a women's menstrual cycle. The basic break down is that when hormones mixtures are not distributed correctly for the person's body then it is very likely to influence the individual's decision in committing a crime. (Schram & Tibbetts, 2014)
Does this make sense in biosocial models of criminality?
The biosocial model tries to explain criminal and antisocial behavior by exploring both biological factors and environmental factors. Genetics do not make people choose to commit a crime, however, there is defiantly a correlation between behavioral genetics and criminal
