F Statistics in Drosophila buzzatii: Selection, Population Size and Inbreeding

Drosophila buzzatii is confined to reproducing in a well defined patchy environment consisting of rotting cactus cladodes which are ephemeral, permitting at most three generations. Flies emerging from such rots were used to estimate the additive genetic variance within rots and the genetic variance between rots for body size and also were electrophoresed to determine their genotypes at six polymorphic loci. F statistics were estimated from body size and allozyme data. The F(ST) derived from body size was significantly larger than the allozyme F(ST). It is proposed this is due to selective differentiation of body size. The allozyme F(ST) is used to estimate effective population size: 10 < N < 50. It is suggested that the regularly observed positive F(IS)'s could be due to partial sib mating, S. If so, the estimated lower bound is S = 0.258. Experiments are identified which could support or contradict these interpretations.
