Our unique genes amplify themselves through environment

It is one of the crowning findings of behavioural genetics: the older we get, the more our specific genetic differences are associated with the degree to which we differ on measured phenotypic traits; like weight, disease prevalence and cognitive diversity. This is interesting, because genetic variance of a population doesn’t change over time (each person … Continue reading Our unique genes amplify themselves through environment

An Intelligent Paradox Yielding Progress.

Studies of intelligence quotient (IQ) differences in a population seem to entail that the variance of intelligence between individuals is predominantly the effect of genetic difference. In fact, genetic variance is said to account for almost 80 per cent of the IQ variances in the population, leaving just 20 per cent of the variance to … Continue reading An Intelligent Paradox Yielding Progress.
