Capability of brain as an organ is immense. It is a matter of personal inclination . Environment in such matters is more decisive in success than the genes.
it is not a matter of gene. just read a little bit on education in the family. we have hidden curriculum. they succeed more in educational attainement, achievement. money in these type of family encourage the children more to pursue in term of career.
but a rich and intelligent family does not provide a 100% intelligent child.
I do not understand much about inheritance of intelligence but i sure think that intelligence is passed on from previous generations. Intelligence is intrinsic and not taught
Genes are responsible for transmission of characters from parents to children including intelligence also. But In recombination of characters there is always variation. it is not always possible that intellectual parents' kids get genes for Intelligence. Apart from this environmental factors, social, mental and emotional development are also important in intelligence.
According to the PhD Pratap Naikwade, intelligence can be transmitted from father to son, but the recombination of maternal and paternal genes can make intelligent parents born less intelligent children and vice versa. In addition, intelligence is not something unique, but it has many variants and should be spoken of in the plural, not in the singular. On the other hand, there are aspects of that cocktail that we call intelligence, which are acquired through experience, social relations and education. The brain can be "educated" to get better performance.
By genetic theory, sons of academician's doughters will have a chance to be successful in science. Brain ability is inherited via females in the next male generation. But only a chance without a guarantee! Level of children's education depends on mother's respect to father's occupation in science and is not directly correlated with their ability to deep analysis of complex things.
The cunning father from the academic point of view can generate a child with such intelligence potential, that during his family education and after schooling, he will be able to develop all his intellectual and emotional potential up to a great level, to the degree that as a person he could finish also in being a great academic
I think this is maybe a nature AND nurture answer. I think the probability of two intelligent people having an intelligent child is high because of genetics.... but I also think that two intelligent people would provide a good learning environment for their child, help with homework, provide a tutor if necessary, expect their child to go to college and do well in life. Even if the parents were of average intelligence, giving a child the love, encouragement and support to do well usually works.
If we are talking about intelligence as measured by IQ tests, the old rule of thumb was that the mean of the children's intelligence(s) would approximate to the mean of the parents' intelligence(s). However, this can only be seen if you average a lot of family data. For a normal family with a small number of children, there is an equal chance that each child's intelligence will be above or below the parents' mean, with the distance above or below the mean approximating to the normal curve in probability. So you can have more than one child above or below the mean, just as you can have a run of heads or tails when tossing a coin. However, as others have pointed out, this is based on genetic factors and does not take into account that the better health and more stimulating environment provided by highly intelligent parents can boost the functional intelligence of the child - or hinder it if the parents are of lower ability and thus earning power.
Nature and nurture likely play a part, but there is always the outlier who academically achieves despite parenting, or does not achieve despite parenting.
In response to Dr. Amir, the examples are of genius which are outliers. Beethoven was raised by an abusive father who wanted him to be a prodigy like Mozart; Michelangelo was an orphan who worked along side artists who nurtured his talent along with a number of other sponsors. He received commissions for his art while still a teenager.
Not necessarily, the influence of society is important, not only is genetics important but the phenotype, what we should do as parent researchers is to try to give more time to our children, this is difficult for us who spend a lot of our day researching
A brilliant question which is very common in societies today. You know, there is a saying in India (my country), which goes like so: "Chiraag tale Andhera".
Translation: "Just below the lantern, lies the darkness".
I would like to answer this question using the above mentioned analogy. It is not mandatory that perspicacious parents always give birth and rise to sagacious children. Every individual is unique and has different abilities. The lantern illuminates rooms, but, beneath is all dark! The lantern is the parent and its darkness their children.
The question that you have raised here is just a MYTH!
Genetic heredity and environmental factors have a great bearing on children. The children of educated parents tend to enjoy a sharper mind. However, we can never judge human potentialities based on general rules. Humans have a byzantine character which sometimes defies scientific generalizations.
Genetic inheritance is important, but not everything. The combimation of the genetic load of both parents is "capricious" and in it chance has a great role. Smart parents can be born clumsy children and viceveresa. History is plagued by great isolated minds in little bright family trees.
Another thing is that a bright mind is more likely to be exploited if born in a family with a high educational level than if it was in a family of low educational level. But, even then, there is an absolute cause-effect relationship.
Most examples I know show that there is no cause-effect relationship in this regard. We can "control" the way we grow our children, we try to give them "the" good example, but lastly, most factors are beyond our ability to manage: ambitions, intellectual abilities, social atmosphere, economic attractiveness, desires and will ...
