Chromosome theory represents an example of the modern approach to heredity theory.Chromosomes which are composed of DNA contain the genetic code for human gender differences. Gender is determined from chromosomal arrangements so that women typically have an XX pattern and men have an XY pattern. Some people have anomalous patterns which include XXX for some women and XXY for some men During the 1960s scientists investigated the t heoretical implications of the XYY pattern Research was reported in 1965 suggesting that XYY males are more prevalent in prison populations than in society.27 These super males were reported to be more aggressive than typical XY males and therefore more prone to criminal devuance than XY males Subsequent research challenged these findings and the methodology used in particular the factthat less than 5% of males exhibit this pattern and therefore the theory has little predictive value.28 However chromosome theory represents an important example of how modern scientific knowledge can be used to update older theories Research continues on possible connections between chromosomes and criminality
