Abstract:
:The parasitoid wasp Nasonia vitripennis is an emerging model organism for developmental and behavioral genetics. It reproduces by haplodiploidy; males typically develop parthenogenetically from haploid eggs and females from fertilized diploid eggs. A polyploid mutant strain is available in which females are triploid and lay haploid and diploid eggs that normally develop into males when unfertilized. In contrast to previous reports, approximately 2% of triploid females were found to occasionally produce daughters as well as gynandromorphs from diploid unfertilized eggs. Daughter production increased with age and differed among familial lineages. This is the first report of parthenogenetic female development in Nasonia. The results show that a paternally provided genome is not required for femaleness and call for modifications of existing models of sex determination in Nasonia.

GENETICS文献大全abstract::Inactivation of the maternal or paternal X chromosome in a mammalian embryonic XX cell is believed to involve random choice between the two X's. We propose two alternative models. One suggests that choice is not random, while the other is consistent with random choice, but not one between two X's. ...
