“Mosquitoes ‘lured by body odor genes’,” BBC News reports. Researchers tested a series of non-identical and identical twins, and found identical twins had similar levels of attractiveness to mosquitoes.
Researchers have long known that some people are more attractive to mosquitoes than others, and some think this is to do with body odor.
Body odor is, in part, inherited through our genes, so the researchers running this study wanted to find out whether twins with identical genes shared a similar level of attractiveness to mosquitoes.
They exposed the hands of sets of identical and non-identical twins to mosquitoes to see which twin the mosquitoes preferred.
The results showed identical twins were likely to have about the same level of attractiveness to mosquitoes, while non-identical twins’ results differed more. This strongly suggests there is a genetic component, in the same way there is for height and IQ.
