Children get their intelligence from their mothers, claims a new study. Women are likely to transmit intelligence gene to their children because they are carried on the X chromosome. Women have two chromosomes, while men have only one.
Scientists believe that genes for advanced cognitive functions which are inherited from the father may be automatically deactivated.
‘Women are more likely to transmit intelligence genes - which are carried on the X chromosome- to their children as they have two of these while men only have one.’
AdvertisementIn some cases, a category of genes known as conditioned genes works only if they come from the mother and sometimes from the father. Intelligence is among the conditioned genes that come from the mother.
Genes are not the only determinant of intelligence. Only 40 to 60 percent of intelligence is estimated to be hereditary, leaving a similar chunk dependent on the environment.
Mothers play a significant non-genetic part of intelligence. Studies suggest that a secure bond between mother and child is intimately tied to intelligence.
