Oops, I just learnt from the article that a child takes intelligence genes after its mother, not father. Now I understand why my kids sometimes create problems when it comes to education etc !!!
www.independent.co.uk/news/science/children-intelligence-iq-mother-inherit-inheritance-genetics-genes-a7345596.html A mother's genetics determines how clever her children are, according to researchers, and the father makes no difference. Women are more likely to transmit intelligence genes to their children because they are carried on the X chromosome and women have two of these, while men only have one. But in addition to this, scientists now believe genes for advanced cognitive functions which are inherited from the father may be automatically deactivated.
