Brad Pitt, Tom Cruise, Roger Federer, George Clooney and fruitflies. They all have something in common: Yes, it is the presence of good genes.

According to various studies, it has been said that attractive as well as good looking male fruitflies have an ability to pass their attractive traits on to their male offspring. And the same trend is true for other species, also.

Recently, a lot of researches were conducted at the University of Exeter in Cornwall. They were involved in the observation of the mating behavior of fruitflies.

They matched a lot of males and females together randomly, in order to see how long it takes for the pairs to mate. The research states that the period of time that was involved in the whole mating process  ranged from two minutes to even two hours. It is a fact that the female fruitflies should make themselves available in order to mate, otherwise the males cannot force the whole process on them.

This whole time that was  for by the pairs to mate was taken as an indication of the male perceived
attractiveness by the female, according to the researchers.

These times are compared with those of the flies sons. They found a correlation between the mating times of the father as well as the son. According to this correlation, it was suggested that attractiveness is hereditary.

It is possible that one cannot describe attractiveness with the help of individual characteristics alone. It is a fact that there is no such particular physical trait that female fruitflies are looking for in a mate.

“However, there is clearly a benefit to females in having sexy sons that are more likely to attract a mate and produce offspring,” David Hosken, Ph.D. of the University of Exeter, was quoted as saying.

Now that it has been produced that a genetic link has been established within the fruitfly population, there is a belief that this trend could translate to other species as well... Humans, for example!

“It is possible that attractiveness is hereditable across the animal kingdom. It could even be the case in humans that the sexiest dads also have the most desirable sons,” Dr. Hosken said.
