Yes moms, we know this won't come as any kind of shock to you but children inherit intelligence from their moms, not their dads.
But science has finally backed up what we knew all along - that children get their intelligence from their mother.
And it's all down to chromosomes.
Children inherit intelligence from their moms, not their dads
Females have XX chromosomes whilst males have XY chromosomes, and multiple studies have shown that the X chromosome is responsible for carrying intelligence.
This means that females are twice as likely to pass down intelligence to their children than fathers are.
And there's no point in men trying to dispute that children inherit intelligence from their moms, not their dads - as a number of studies have reached this conclusion over the years.
Mom's IQ
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 in most scenarios was the child's mother - and that the young people's IQs were only around 15 points different from that of their mothers.
Environmental factors
However, some disagree with the idea that mum's are the ones who pass down intelligence, arguing that there are many more factors than simply genetics in determining a child's intelligence.
According to Psychology Spot, it's estimated that 40-60% of intelligence is hereditary - the rest comes from our environment.
Harsh parenting
Harsh parenting practices in childhood have long-term repercussions for children’s brain development, a study has shown.
Repeatedly getting angry, hitting, shaking or yelling at children is linked with smaller brain structures in adolescence, according to a new study published in Development and Psychopathology.
It was conducted by Sabrina Suffren, PhD, at Université de Montréal and the CHU Sainte‑Justine Research Centre in partnership with researchers from Stanford University.
