On the matter of intelligence, studies have shown that it (intellegence) is inherited through the female side.
No, research has NOT established that you inherited your intelligence
from your mother.
A garbled post from a website called Second Nexus has gone viral,
probably because of its eye-catching headline claim that “New Research
Establishes That Intelligence Is Inherited From The Mother.” The piece
is by-lined “Editorial Staff,” presumably because everyone was too
embarrassed to put a real name on it.
The erroneous premise of the post seems to be that science has traced
“intelligence genes” to the X chromosome.
Quote:Mothers do tend to have two X chromosomes, but they aren't identical
chromosomes, and of course, they got one of them from their fathers.
Mothers generally pass only one X to their children (after the two X
chromosomes engage a little genetic swapping themselves), and those
children in turn receive the second sex chromosome (X or Y) from their
fathers. Whatever is on the X can pass from mother to child or father
to (usually) daughter, but the two X chromosomes the mother has aren't
the same and don't at all automatically double the odds of inheriting a
specific variant.
