Female behaviour and the interaction of male and female genital traits mediate sperm transfer during mating.

abstract：:Laboratory studies on Drosophila have revealed that resistance to one environmental stress often correlates with resistance to other stresses. There is also evidence on genetic correlations between stress resistance, longevity and other fitness-related traits. The present work investigates these associations using art...
