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.

The genetic aspect of IQ is vastly more important than any environmental factors, and Prof Donohoe believes that these are the first of many genes for IQ that will be identified by scientists in coming years.

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