Thought: The FoxL2 Gene and Criminals
Sunday, December 13th, 2009A recent scientific finding published on the journal Cell describe a gene in female, FoxL2, which when turned off, can unleash the male gene Sox9. The ovaries of a female mice without FoxL2 become testes, producing same level of testosterone as male mice. Minnie becomes Mickey.
That caused me to think some social issues. First, China has a problem with preferring boys over girls. Because of deep cultural tradition and perception of a son over daughter in elderly care, parents want to have boys. But when the boys grow up, there too many boys, and they need girls to get married. What if, with the switch of a gene, the hospital switch the gender of babies when they are little. When they grow up, they switch back, so everyone is happy. It is just like some of the fish which can “switch sexes at times when there is a scarcity of either males or females”.
Second, what if we turn on FoxL2 in male? Will that turn off Sox9 gene and testosterone in male, turning man into woman? It is a fact that, compared to women, men are predominantly the aggressors in the society, causing various social problems (crimes, wars, etc.). Rather than keeping men in prison, what if we give them a gene therapy, just turn off their Sox9? Is this a humane solution?
Certainly, there are broader considerations for both of these solutions. The China population issue, the real solution might be to give people real insurance when they grow old, and to change the cultural view on girls. For the crime solution, education might be more fundamental than mere gender switch.
