White men are drawn to the facial features of Asian women, scientists reveal.
During the study, the researchers found that white people tend to choose other races when asked to rate which faces they find most attractive.
Men and women aged between 18 and 30 were shown 600 faces of the opposite sex and asked to grade them for attractiveness.
Men plumped for Asian women, followed by white, then black.
The Department of Psychology at Cardiff University, which carried out the study, said that the results of their research are reflected in society.
Government figures show around one-and-a-half times more black men marrying white women than the other way around in the UK.
More white men have also been found to marry East Asian women - compared to Asian men marrying white women.
"It will come as no surprise to many that facial attractiveness makes up part of the decision of who we marry," the Daily Mail quoted Michael Lewis, the study leader as saying.
"And it's no coincidence that groups perceived as more attractive - black males and Asian females - feature more often in mixed-race marriages.
"In the past more measurable features such as wealth, status and fertility have been considered more important in how we choose out partners.
"Our study matches the same patterns observed in the Government's data on marriage," he added.
