Scientists Have Found That Intelligence Is Passed From Mothers

This article may anger a couple of dads, but according to a recent genetic study. we probably inherit our log of intelligence from the female X chromosome.

The X chromosome contains a thousand genes, and great number of them have an impact on perception. Until now, most doctors believed that parents contribute equally to their child’s intelligence.This research has been proven both correct and disputable.

Most studies indicate that genetics is a highly complex and demanding field of research. Despite strong disagreement on the subject, it’s best to approach these studies from an objective perspective. So, it’s helpful to present a couple of key facts about how X and Y chromosomes work. A chromosome is a thread-like formation composed of nucleic acids and protein. They store and transfer genetic information. Every person has one pair of chromosomes in each cell of their body. The females have two X chromosomes, the males have one X and one Y chromosome.

As a rule, the genetic characteristic of gender-specific genes, like humans have, are either activated or deactivated depending upon the specific selection and, later on, the genetic properties being affected.The activated genes will have an impact on the genetic development, while deactivated genes will not. So if a single characteristic is affected via the mother, the fatherly genes are deactivated. At the opposite side, if a single feature is affected via the father, the maternal genes are later deactivated. The structure of these gender-specific genes forms the foundation of intelligence research. Women are apparently more likely to have an impact on cognitive abilities, as women possess two X chromosomes, while men carry just one. There is certainly more to this theory of intelligence genetics than just X chromosomes.

This is where gender-specific genes come in. Intelligence is thought to be a highly-gender-specific gene that comes directly from the mother. Scientists used genetically-modified mice to test this theory through a study. They found that embryonic test subjects, which were administered mainly maternal genetic chromosomes, developed an improperly larger skull and brain while developing a much smaller body.

Subjects treated with larger amounts of paternal genetic material developed a larger body, but a smaller skull and brain. In addition to this, researchers made other significant observations, like identifying six areas of the brain what contain exclusively either maternal or paternal genes.

The theory that mothers have an asymmetrically large  influence on a child’s intelligence is not a new one. In 1984, the University of Cambridge studied both brain development and genomic conditioning. The scientists ultimately concluded that maternal genetics provide more material to brain centers. Similar discoveries are being made to this day. In a particularly informative study, researchers from a government agency which followed a group of 12,686 people aged 14 to 22. Each year, researchers interviewed the subjects and monitored how their intelligence developed, taking into account their educational and ethnic backgrounds. They categorically concluded that a mother’s IQ the best indicator of high intelligence.

It’s certain that this theory won’t be widely accepted by everyone, even if it’s unquestionably proven. There is however one certain fact that can be deduced from all this, and that is that mothers have a significant influence on their children’s cognitive capacity. And it’s not just because of genetics, either. Nutrition and nurture influence a child’s intellectual development constantly throughout life.
Even more so, the special bond between a mother and child provides motivation for them to explore the world and solve problems together. Women play a much larger part in the child’s intellectual development,than genetics studies give them credit. All signs show that our mothers give us brainpower.Thanks, Mom!…

Girls may inherit ovarian cancer gene from fathers

Scientists have found a gene responsible for ovarian cancer that can be passed down from fathers to their daughters.
The study found that genes on the X-chromosome get potentially passed down through the father to his daughter, thus increasing the risk of ovarian cancer in girls.

A mutation on the X-chromosome may also advance ovarian cancer's age of onset by more than six years.

"Our study may explain why we find families with multiple affected daughters: because a dad's chromosomes determine the sex of his children, all of his daughters have to carry the same X-chromosome genes," said an Assistant Professor.


The study,  stated that the genetic mutation inherited from the paternal grandmothers were also associated with higher rates of prostate cancer in fathers and sons as well.

The researchers collected information about pairs of granddaughters and grandmothers and sequenced portions of the X-chromosome from 186 women affected by cancer. 

The results proposed that a gene on the X-chromosome may contribute to a woman's risk of developing ovarian cancer, independently of other known susceptibility genes, such as the BRCA genes.

This observation suggests that there may be many cases of seemingly sporadic ovarian cancer that are actually inherited, and may lead to improved cancer screening and better genetic risk assessment.
 
However, future studies will be needed to confirm the identity and function of this gene. 
"What we have to do next is make sure we have the right gene by sequencing more families. This finding has sparked a lot of discussion within our group about how to find these X-linked families," the Prof. said. 

"It's an all-or-none kind of pattern: A family with three daughters who all have ovarian cancer is more likely to be driven by inherited X mutations than by BRCA mutations," the Prof. noted.
