If you believe the statistics, in the United States harsh methods of Providence educational work began to appear from 2007 to 2009, and it was exactly those women, whose blood has a genetic anomaly "evil mother". However, different variations of a gene DRD2 have 50% of mothers, so here it is hard to make clear that the cause of the crisis, stress and so on.
However, cost and economic background in the country to become positive, as many women with the gene mutation has become more reserved and quiet, aggression to their own children did not show. During the experiment it was investigated about 5000 of those born in the period from 1998 to 2000, including their mothers. We studied took saliva to detect the presence of gene mutations in their DNA.
