Is IQ inherited or learned?
Researchers have previously shown that a person’s IQ is highly influenced by genetic factors, and have even identified certain genes that play a role.
They’ve also shown that performance in school has genetic factors.
But it’s been unclear whether the same genes that influence IQ also influence grades and test scores..
What does a girl inherit from her father?
As we’ve learned, dads contribute one Y or one X chromosome to their offspring. Girls get two X chromosomes, one from Mom and one from Dad. This means that your daughter will inherit X-linked genes from her father as well as her mother.

What do twin studies tell us about behavior?
Modern twin studies have concluded that almost all traits are in part influenced by genetic differences, with some characteristics showing a stronger influence (e.g. height), others an intermediate level (e.g. personality traits) and some more complex heritabilities, with evidence for different genes affecting …
How genetics and environment influence the similarities and differences within twins?
Any differences between identical twins is expected to be due to environmental factors since they are genetically identical, whereas fraternal twins only share half of their genes on average. … When a genetic influence is dominant, the identical twins would have more trait similarity than fraternal twins.
What do twin studies reared together and apart Tell us about behavior?
A powerful method is studying identical twins reared apart from birth. Reared-apart identical twins resemble one another only because of their shared genes. Interestingly, research shows that identical twins reared apart and together are about equally similar in personality traits such as aggression and traditionalism.
