Reproductive Diapause in Drosophila Robusta

Chromosome interactions in Drosophila robusta.

M O S T of the population genetics work on Drosophila species has been done with polymorphism at a single gene locus or different gene arrangements in one chromosome which behave in inheritance as single genetic units. However, little attention has been given to the problem of interactions between unlinked polymorphic loci. Consider two unlinked autosomal loci A and B and their variant alleles ...

Reproductive skew in the Australian allodapine bee Exoneura robusta

Uneven sharing of reproduction (reproductive skew) among members of a cooperative animal society is one of the key features associated with advanced sociality and task specialization. Allocation of reproduction varies greatly among taxa, and reproductive skew models are evolutionary models that aim at explaining this variation. We tested reproductive skew theory using the Australian social allo...

Sexual Selection Operating in a Wild Population of Drosophila Robusta.

Almost 60 years have elapsed since the discovery of variation in the polytene chromosomes of Drosophila (Sturtevant and Dobzhansky 1936). Inversion polymorphism studies have revealed some of the intricacies of evolutionary change, but even now, when interest in them has waned, there is little understanding of the particular alleles contained within them that alone or in relation to other genes ...
