Spermatogenesis in haploid males of the jewel wasp Nasonia vitripennis

Abstract Males of hymenopteran insects, which include ants, bees and wasps, develop as haploids from unfertilized eggs. In order to accommodate their lack of homologous chromosome pairs, some hymenopterans such as the honeybee have been shown to produce haploid sperm through an abortive meiosis. We...
