According to a new research the descendants of females who are given a choice to select their partners live longer than those who are not given the choice.The research involves the humble fruit fly, but experts believe it could have inkling for the human espousal game.
Geneticists from the University of Georgia, led by Dr Daniel Promislow, put one virgin Drosophila melanogaster, a variety of fruit fly, in a vial with one virgin female. Some of the females disapproved to asociate altogether, despite the fact that fruit flies are prominent for their proclivity for mating almost any time and at any place.
AdvertisementThey put some females in tubes with seven males so that female choice and male contest could come into action. The experiment was carried out on fruit flies of a wide variety of age groups. The scientists measured offspring in terms of their viability, their wing size, asymmetry of features and the number of tooths on their sex combs which are used to purport females.
The main difference between offspring was that those whose mothers had been able to pick their mate were more likely to live longer. Dr Promislow, said "Our results focus on adults, and we showed that the process of sexual selection can lead to a genetically related increase in the components of adult fitness."
