Polyandry as a hedge against genetic incompatibility
Why do females across a wide range of taxa mate with more than one male? Here, I present the hypothesis that females engage in polyandry as a hedge against genetic incompatibility. I review evidence from the literature ...
Grooming, aggression, and genetic relatedness in Parachartergus colobopterus, a neotropical swarm-founding wasp
I examined biting, grooming, and inspection behavior in a pre-emergent colony of Parachartergus colobopterus, a neotropical swarm-founding wasp, to determine whether kin discrimination occurs between adult colony members. ...
Genes expressed during oogenesis in Calliphora erythrocephala and Drosophila melanogaster
We were interested in identifying genes in the dipteran flies Calliphora erythrocephala and Drosophila melanogaster with a role in oogenesis and early embryogenesis. A biochemical screen was used to complement the extensive ...
The structure and sequence of the single calmodulin gene of Drosophila melanogaster
The work described involves the isolation and characterization of the gene encoding the calmodulin protein in the dipteran species, Drosophila melanogaster. The two major protein coding exons, designated 2 and 3, had been ...
Characterization ofbicaudal, a maternal effect mutation of Drosophila melanogaster
The Drosophila melanogaster mutation bicaudal (bic) is the founding member of the group of maternal effect mutations that disrupt anterior-posterior axis formation by creating mirror image duplications of posterior segments ...
