INTELLIGENCE DEPENDS ON GENETIC FACTORS.

QUALITY ANSWER REQUIRED
Answers
genes play an important role in determining the physical and mental characteristics. About 40% of a child's IQ depends on genes. intelligence is a complex trait that is influenced by both genetic and environmental factors. suppose your father is very poor and your mother is also poor but intelligent. Because of poverty he could not get proper education.Now the genes of your mother enabled you to become what he is today.
Imagine you have a number of necklaces with 20,000-25,000 similar beads strung together. Now imagine you are looking for 3,000 specific beads on each necklace, but you're not sure what they look like or even if they will look the same on each necklace. This is a bit like trying to find the genes that influence our intellectual abilities.
Intelligence is challenging to study, in part because it can be defined and measured in different ways. Most definitions of intelligence include the ability to learn from experiences and adapt to changing environments. Elements of intelligence include the ability to reason, plan, solve problems, think abstractly, and understand complex ideas. Many studies rely on a measure of intelligence called the intelligence quotient (IQ).
At last, It is clear that both environmental and genetic factors play a part in determining intelligence.

Like most aspects of human behavior and cognition, intelligence is a complex trait that is influenced by both genetic and environmental factors.
Intelligence is challenging to study, in part because it can be defined and measured in different ways. Most definitions of intelligence include the ability to learn from experiences and adapt to changing environments. Elements of intelligence include the ability to reason, plan, solve problems, think abstractly, and understand complex ideas. Many studies rely on a measure of intelligence called the intelligence quotient (IQ).
Researchers have conducted many studies to look for genes that influence intelligence. Many of these studies have focused on similarities and differences in IQ within families, particularly looking at adopted children and twins. These studies suggest that genetic factors underlie about 50 percent of the difference in intelligence among individuals. Other studies have examined variations across the entire genomes of many people (an approach called genome-wide association studies or GWAS) to determine whether any specific areas of the genome are associated with IQ. These studies have not conclusively identified any genes that have major roles in differences in intelligence. It is likely that a large number of genes are involved, each of which makes only a small contribution to a person’s intelligence.
Intelligence is also strongly influenced by the environment. Factors related to a child’s home environment and parenting, education and availability of learning resources, and nutrition, among others, all contribute to intelligence. A person’s environment and genes influence each other, and it can be challenging to tease apart the effects of the environment from those of genetics. For example, if a child’s IQ is similar to that of his or her parents, is that similarity due to genetic factors passed down from parent to child, to shared environmental factors, or (most likely) to a combination of both? It is clear that both environmental and genetic factors play a part in determining intelligence.
