Australian and Canadian researchers have conducted a study on fruits flies. On the basis of it, the researchers have stated that excessive male attention can prove negative for pretty females.

The study researchers conducted experiments in which they different groups of flies to adapt to a new environment in the lab of the university of 13 generations. The researchers manipulated the number of potential mates in each group, by this they regulated the possible harassment rate.

Study researchers have even sequenced genomes of the flies. Upon assessment, they have found a number of genes that became more common when harassment was not done. But when the harassment took place, the same genes became rare.

Steve Chenoweth from the University of Queensland's School of Biological Sciences said that male aggravation of females created problems to the species' ability to adjust to new environmental conditions. It was also found that increased male attention stopped the flies from adapting.

"Female fruit flies with superior genes that allow them to lay more eggs were so attractive to male suitors they spent most of the time fending off male suitors rather than actually laying eggs", said Steve.

Study researchers said that the future prospects of the study involved revealing the exact gene functions involved and also, to know more about the connections between male and females.
