Intelligence can be defined as the ability of a person to think clearly, plan, solve problems, learn from experiences, function effectively in the environment, understand and handle abstract concepts, and adapt to new situations.
Much of the excitement among researchers in the field of intelligence results from their attempts to conclude exactly what intelligence is.
While it’s one of the most discussed topics in psychology, there’s actually no standard definition of what exactly constitutes intelligence. It’s challenging to study, in part because it can be measured and defined in different ways.
Like many aspects of human cognition and behavior, intelligence is a complex trait that’s affected by both environmental and genetic factors. Nearly 40-60% of intelligence is inherited — with the remaining percentage depending on personal traits, stimulation and environment.
Researchers have carried out many studies to look for genes that affect intelligence. One of the first studies in this field was done about 35 years ago at the University of Cambridge, followed by many other studies over the years. In the studies, the co-evolution of the brain as well as the conditioning of the genome have been examined.
According to researchers, maternal genes are responsible for thought center development. Most of a kid’s intelligence depends on the X chromosome.
A chromosome is a thread-like formation, which has protein and nucleic acids. It transfers and stores genetic information. Everyone normally has one pair of sex chromosomes in every cell. Males have 1 X and 1 Y chromosome, whereas females have 2 X chromosomes.
The X chromosome is one of the 2 sex chromosomes in people. The sex chromosomes form one of the 23 pairs of human chromosomes in every cell. In addition, the X chromosome spans more than 150 million DNA building blocks as well as represents around 5% of the total DNA in cells.
Intelligence genes are located on the X chromosome. And women are twice as likely to transmit intelligence genes to their kids, since they have 2 X chromosomes.
