| Abstract: | Background Despite the two-fold cost of sex, most of the higher animals reproduce sexually. The advantage of sex has been suggested to
be its ability, through recombination, to generate greater genetic diversity than asexuality, thus enhancing adaptation in
a changing environment. We studied the genetic diversity and the population structure of three closely related species of
bag worm moths: two strictly sexual (Dahlica charlottae and Siederia rupicolella) and one strictly asexual (D. fennicella). These species compete for the same resources and share the same parasitoids. |
