Definately not! There’s no link between the genes for hair colour and any genes that could be potentially be related to intelligence – the ‘dumb blonde’ is an out-of-date stereotype. Besides, intelligence is very much affected environmentally affected – it’s largely to do with how you are brought up, social factors, and how much you want to learn!
Hi kyna. Hair colour is largely genetic (natural colour anyway), and while there is a genetic component to intelligence, it also depends on environmental factors that have nothing to do with genes. I’ve seen no reliable evidence for any sort of relationship between hair colour and intelligence. Do you know of any?
