London: According to a recent study, there’s actually a scientific reason kids inherit their intelligence from their mums. Sorry dads. Research has shown that the X chromosome is responsible for carrying intelligence, reports the Mirror. Women have two of these chromosomes (XX) and men have only one (XY) so they are twice as likely to pass down intelligence to their children than the fathers are.
So if you’re looking for a way to win the argument, mums, this could be it. There have been several studies that have sought to prove the theory over the years. One study at the Medical Research Council Social and Public Health Sciences Unit in Glasgow revealed that kids’ IQs tend to be similar to their mothers’.
Researchers interviewed kids every year from the age of 14-22, taking into account various factors like education and socioeconomic status. They found that the best predictor of intelligence was their mothers – and the young people’s IQs were only around 15 points different. But not all scientists agree on this basic X chromosome principle.
Other researchers have highlighted genetics are not the only factor in determining a child’s intelligence. According to Psychology Spot, it’s estimated that 40-60 percent of intelligence is hereditary – the rest comes from our environment. So dads, don’t be glum, you can still play a very important role in your children’s emotional and intellectual development by building confidence, playing, and teaching them new skills.
