Can intelligence be passed down genetically?
General intelligence definitely runs in the family. Twin studies (on both identical twins and fraternal twins) have found a heritability of IQ between 57% and 73%, and in some cases, even higher. Interestingly, genetic studies have revealed that a child's IQ score is less affected by intelligence genes than an adults.
How much of your IQ is genetic?
Researchers have long known that intelligence is highly heritable, meaning much of the difference between your IQ and someone else's — about 40 to 80 percent, depending on your age — is explained by genetic differences.
Are we born with intelligence?
Like most aspects of human behavior and cognition, intelligence is a complex trait that is influenced by both genetic and environmental factors. These studies suggest that genetic factors underlie about 50 percent of the difference in intelligence among individuals.

Do siblings have a similar IQ?
A total of 505,440 males (born between 1950 and 1985) had their IQ scores analyzed and compared to those of their brothers. The authors suggest that siblings who are close together in age may have comparable IQ scores because, being so close in age, they may be having similar experiences.
At what age does intelligence decline?
Smaller improvements are still noticeable from age 20 until what the researchers described as a “peak” begins at age 35. The peak lasts until roughly age 45, at which point chess skill – and, the study theorizes, overall mental performance – begins a marked decline.
Can a normal person become a genius?
David Shenk, author of The Genius in All of Us, says it's virtually impossible to determine any individual's true intellectual limitations at any age; anyone has the potential for genius or, at the very least, greatness. Increasing your intelligence–even taking yours to genius status–takes a willingness to do the work.
Is hair inherited from mother or father?
One popular myth is that hair loss in men is passed down from the mother's side of the family while hair loss in women is passed down from the father's side; however, the truth is that the genes for hair loss and hair loss itself are actually passed down from both sides of the family.

Studies examining the link between family size and intelligence have consistently found a negative relationship. Children born into larger families tend to score lower on intelligence tests than children raised in smaller families.
Is the oldest child always the smartest?
Oldest children are the smartest, research shows
Research published in the Journal of Human Resources found that firstborn children outperform their younger siblings on cognitive tests starting from infancy — they are better set up for academic and intellectual success thanks to the type of parenting they experience.
Can a child have a higher IQ than their parents?
But genetics can explain the wide range of possible IQs too because so many different genes are involved in developing and running a brain. It is possible, for example, to inherit all the higher IQ genes from each parent and leave the lower IQ ones behind. Now the child will be brighter than the parent.
