A study has been done on whether people can recognise a gay person instantly and in the majority of cases they can - even when facial pictures only are turned upside down.
Perhaps genetic tests should be conducted to see whether there is an altering of chromosones that aren't apparent in a heterosexual person? In my opinion the eyes are a giveaway in males - although with females it seems harder to pick.
MOST people possess an automatic ''gaydar'' that assesses sexual orientation in less than a blink of an eye, research has shown.
In tests, scientists found that gaydar works on an unconscious level and is more accurate when directed at women.
Volunteers asked to distinguish between photos of ''straight'' and ''gay'' faces were able to do so in just 50 milliseconds - a third of the time of a blink.
Their accuracy remained greater than chance even when the photos were upside-down.
For women's faces, participants were 65 per cent accurate in guessing sexual orientation when the photos were flashed on a screen.
Differentiating between gay and straight men turned out to be harder. In this case, gaydar got the answer right only 57 per cent of the time.
The research, published in the online journal Public Library of Science ONE, involved 129 college students. They were each shown 96 photos of young men and women who identified themselves as gay or straight.
US psychologist Joshua Tabak, who led the study at the University of Washington, said: ''It may be similar to how we don't have to think about whether someone is a man or a woman or black or white.''
Only photos of people without ''give-away'' clues such as facial hair, make-up or piercings were used in the experiment.

Females who wear very short hair, dungarees and walk like a man are lesbians. All male hairdressers are gay! So it goes ........ who cares?
