Scientists have long suspected a link between genes and IQ, but they have been unable to prove it – until TCD scientists, led by Professor Gary Donohoe, recently identified two genes that are important in determining a person’s IQ.

Dr Emma Rose was part of the TCD team that discovered the link between the two genes and IQ and brain size.
