The study, which has been published in the journal, Psychology Spot dates back to a sample survey done in the year 1994, where close to 12,686 people, aged between 1-22 were interviewed and questioned on several factors including race, education level, socio-economic status and similar questions were asked to mothers in the study. Upon analysis, it was seen that the intelligence gene was linked to the X chromosome, which is the prime female chromosome.
In fact, another correlated study, linked to the 1994 based study found out that women, since they have twice the number of X chromosome are more likely to pass on the intelligence genes onto their children.
