Here’s a reason for mothers to rejoice because all your doubts have been confirmed and sealed with science! Research says that the mother’s genes are responsible for how smart her child will turn out to be. Mommies everywhere, this is your cue to yell, “I knew it!” The research confirms that most of a person’s intelligence is attached to Chromosome X – which is carried by women in a pair. While female children get one of the X Chromosomes from the father, intelligence genes aren't activated when they're passed down by a male. So the next time your child is behaving all goofy, you'll know exactly whom to blame. At least until they find out who passes on the tantrum genes.
