A new study has discovered that female mice, who mate in promiscuous surroundings, bear attractive sons.
Biology professor Wayne Potts, senior author of the new study, said that if your sons are particularly sexy, and mate more than they would otherwise, it's helping get your genes more efficiently into the next generation.
Potts asserted that only recently has his team started to understand that environmental conditions experienced by parents can influence the characteristics of their offspring.
"This study is one of the first to show this kind of 'epigenetic' process working in a way that increases the mating success of sons," Potts said.
Male mice whose parents freely competed for mates in seminatural "mouse barns" produced 31 percent more major urinary proteins or MUPs, sex attractants called pheromones, than male mice from caged monogamous parents, the biologists report.
The study is published in the journal Proceedings of the National Academy of Sciences. (ANI)
