Type | 0=pregnant, 1=virgin, 9=none |
Longevity | Lifespan (in days) |
Thorax | Length of thorax (in mm) |
Sleep | Percent of day sleeping |

Details
Hanley and Shapiro (1994) report on a study conducted by Partridge and Farquhar (1981) about the sexual behavior of fruit flies. It was already known that increased reproduction leads to shorter life spans for female fruit flies. But the question remained whether an increase in sexual activity would also reduce the life spans of male fruit flies. The researchers designed an experiment to answer this question. They had a total of 125 male fruit flies to use and they randomly assigned each of the 125 to one of the following five groups.
