WitrynaIn the Hymenoptera (bees, ants, and wasps), males are haploid, meaning they have no father; their single set of chromosomes comes from their mother. Most importantly, a male haplodiploid insect produces sperm that are all identical, whereas a diplodiploid male produces sperm that vary genetically. Witryna1 lis 2000 · Haplodiploid bark beetles are remarkable in that the entire clade of over 1300 species are apparently extreme (sib-mating) inbreeders, most of which cultivate …
Witryna22 lis 1999 · The most–parsimonious trees imply a single origin of haplodiploidy uniting Xyleborini (approximately 1200 species) and sib–mating Dryocoetini (approximately 160 species).

WitrynaMost analyses resulted in a monophyletic Xyleborini, implying one origin of fungus feeding in this tribe. However, clear evidence for a polyphyletic Xyleborus and three more xyleborine genera calls for further revision of xyleborine classification.
