If you have a high IQ you may want to thank your mother.
This is because intelligence, among other genes, comes from your mother or father.
Each person’s genome is made up of about 20,000 genes that determine characteristics that are reflected in their appearance, health and personality.
Some traits are linked to a single gene – such as eye color, freckles and dimples – while others are determined by multiple genes, such as hair color and height.
There are many ways that people inherit genes from their parents.
The first is through the main gene – which only needs to be passed on from one parent for the corresponding trait to be expressed in their child. More genes, in comparison, must be contributed by both parents to be expressed.
Brown eyes are one example of a major genetic trait. If one parent has it, then their child can inherit it. On the other hand, blue eyes are more common – so both parents must carry the gene for their child to have them.
But there are also more complicated forms of genetic inheritance, the most common being X-linked inheritance.
X-linked traits are caused by different types of genes on the X chromosome. Hair color is one example, as well as things like sickle cell anemia or cystic fibrosis.
Children usually inherit 50/50 of their parents’ genes. But some traits come from mothers than from fathers, and vice versa
Intelligence: Mother
Intelligence is another example of an X-linked trait. And because women carry two X chromosomes and men carry only one, women are twice as likely to have traits related to intelligence, research has shown.
A 2006 study by a Medical Research Council Social and Public Health Sciences Unit in Glasgow, Scotland, surveyed 12,686 people between the ages of 14 and 22 every year between 1994 and 2004.
They found that the IQ of each study participant differed 15 points on average from their mothers.
Therefore, researchers found that the strongest predictor of a person’s intelligence is their mother’s IQ.
The famous American actress and filmmaker Jodie Foster and her two sons are an example of this.
He has a ‘genius’ IQ of 132, is said to have taught himself to read at the age of ten and was a high school student.
Her sons seem to have inherited their mother’s wisdom more than the middle one. His eldest, Charlie studied at his mother’s alma mater, Yale University, and is working as an actor. His younger brother, Kit, is a research scientist at Princeton University.
The famous American actress and filmmaker Jodie Foster and her two sons are an example of this. He has a ‘genius’ IQ of 132, is said to have taught himself to read at the age of ten and was a high school student.
But it is not only genetics that affects intelligence.
In fact, a study conducted on twins shows that 40 percent of intelligent people are inherited. Environmental factors account for the other 60 percent, such as education, nutrition and health.
Puberty: Father
Were you an early bloomer? If so, blame your father.
A 2013 study published in New England Journal of Medicine found that mutations in the MKRN3 gene were associated with early onset of puberty, i.e., before the age of eight in girls and before the age of nine in boys.
For this study, researchers analyzed the genomes of 32 people who had reached puberty from 15 families.
They found MKRN3 gene mutations in 15 individuals from five families.
In both cases, the altered gene was inherited from the father.
The researchers concluded that these mutations ‘release the brakes’ on puberty, causing children to begin this chapter of adolescence earlier than their peers.
But like wisdom, genetics is not the only factor that affects the onset of virginity.
Although the cause of puberty is often unknown, other causes of puberty include hormonal drugs, cancer and diet.
ADHD: Mom

If you have Attention Deficit/Hyperactivity Disorder (ADHD), it may be due to genes that affect how your mother’s brain works.
A 2010 study published in the JAMA Psychiatry found that children whose mothers had low levels of serotonin were 1.5 to 2.5 times more likely to have ADHD than those whose mothers had normal levels.
Serotonin is a hormone that carries messages between nerve cells in the brain and throughout the body.
It plays an important role in regulating the mind, sleep. stool and sexual desire.
The production of this hormone is controlled by several genes, but the first ones are TPH1 and TPH2. Some mutations in these genes can interfere with serotonin production, and mothers who have them are more likely to have children with ADHD.
Mel B (Melanie Brown) who was part of the pop group ‘The Spice Girls’ revealed in 2019 that she was diagnosed with ADHD, as well as anxiety, dyspraxia, dyslexia.
Her daughter, Phoenix, told Teen Vogue in 2023 that she was also diagnosed with the disease.
Birth: Father
A daughter’s fertility can be affected by the genes inherited from her father.
Human egg cells contain centrioles, or cylindrical organelles that are included in the formation of spindle fibers during cell division. But this part of the egg is removed naturally during development.
If the centrioles are not removed, then the egg cell will not function.

A 2016 study published in the journal Science found that some women are infertile because they inherit a dysfunctional gene from their father that prevents centrioles from being removed from their egg cells.
Nicole Kidman shared the struggles and pain of infertility, including how she struggled through ectopic pregnancy, miscarriage and failed treatment.
It wasn’t until 2008 when she was 41 that she gave birth to her first daughter through IVF.
Sleeping arrangements: Mother
If you suffer from insomnia, chances are your mom does too.
A 2023 study published in Journal of Child Psychology and Psychiatry found that the children of women with insomnia often have trouble sleeping.
This suggests that children may inherit their mother’s sleep problems.
In fact, about 35 percent of people with sleep disorders have a family history of the disease, and women are the most affected women, according to 2012. comments.
But insomnia is a serious problem that is often caused by a number of factors that change. Just because your mom has it, doesn’t mean you will, just because you increase your risk.
