What utter bilge. IQ genes certainly are not solely X- or Y-linked. ??????!!!!! how is this consistent with *anything* ever, from family studies to SNP heritability to GWAS. And some of it is a lie:
"Concerned that people might not be like mice, researchers in Glasgow took a more human approach to exploring intelligence. They found the theories extrapolated from mice studies bear out in reality when they interviewed 12,686 young people between the ages of 14 and 22 every year from 1994. Despite taking into account several factors, from the participants education to their race and socio-economic status, the team still found the best predictor of intelligence was the IQ of the mother."
The study in question doesn't even have paternal IQ!
