Propositions accompanying the PhD thesis: Polyploidy and host specificity genetics in Nasonia parasitoid wasps 1. Polyploidy is detrimental to the life history of CSD hymenopteran species, but it is more benign in non-CSD species (this thesis). 2. The longstanding paradox of polyploidization being highly deleterious and yet a pervasive force for evolutionary success may be explained by the degree of polyploidization detriment being dependent on its origin (this thesis) 3. Dosage compensation may exist in haplodiploids, as absolute expression of housekeeping genes does not scale to ploidy but is more consistent with the sex of an individual (this thesis) 4. The putative Nasonia host specificity gene(s) (host preference 1) is located in a 4.1Mb odorant-enriched region on chromosome 4, bkbwg9, indicating that parasitoid host specificity is controlled by odorant receptors (this thesis). 5. Don’t waste too much time on the wrong genome (assembly). 6. The dearth of knowledge on non-CSD species is ironic given that most parasitoid wasps, the group with the most potential in biological control, are non-CSD species. 7. The idea that genetics has limited potential for improving biological control is a stubborn, pervasive misconception that should be uprooted. 8. “I don’t believe in Nature either. Or not with a capital ‘N’”. (Crake, Oryx and Crake, Margaret Atwood.) 9. Of the many choices to make in academia, choose patience, and choose forgiveness.
