Thank your mothers for your level of intelligence- as you have probably inherited a chunk of your mental abilities from your mother, according to the researchers at the University of Washington, US.
Fathers, sadly, have very less to offer apart from the favorable environment and surroundings that you were brought up in. In other words, about 40-60% intelligence is hereditary and the rest is dependent on one’s upbringing.
Intelligence is believed to be among a category of genes known as “conditioned genes” that come from the mother. Women are more likely to transmit intelligence genes to their children as they are carried on the X chromosome and women have two of these, while men only have one.
