...views of controversial scientific research, newspapers and television reporters often rely heavily on information supplied by SftP, while rarely giving the organization credit. And they claim it was largely unrecognized efforts of SftP as an organization that were responsible for ending the controversial screening of male babies for the XYY chromosome pattern at the Boston Lying-in Hospital, which is associated with Harvard. Here too, they say, SftP's efforts may have had an effect far beyond the local level: Beckwith says that a recent survey by the Children's Defense Fund found that similar screening programs have been ended...
...have one X (from mother) and a Y (from father). The Y, a tiny, misshapen bit of genetic material, overpowers the X and determines maleness-but little else, although it is widely believed that masculinity includes aggressive tendencies. Nature sometimes slips the conceptus an extra Y to produce an XYY male, almost certain to be well above average height. Because a disproportionately high number of XYYs were found in penal institutions, studies beginning in the 1960s suggested that they may be prone to aggressive criminality. It has taken a decade and a large-scale study by twelve Danish and American...
...recent debate with Jonathan Beckwith, under the auspices of the Harvard Medical Society, was intended to clarify some of the issues raised by his attack on the study of children with an extra Y chromosome (XYY). Your reporter unfortunately added to misconceptions about the study by stating that "A Boston study began in 1969 to inform the parents of babies with XYY chromosomes that males with two Y chromosomes may exhibit criminal tendencies." This distortion is large enough to require correction...
...conclusion is totally unjustified, and that the developmental effects of the extra Y chromosome remain to be determined. One of the tragic features of Dr. Beckwith's attack is that it opposed the kind of study that will be required to correct the popular misconception about the significance of XYY...
Beckwith added that a conversation with the parents of one of 15 XYY children identified in the study "confirmed all the worst fears we had about the study...
