Abstract: ABSTRACT During meiosis, both alleles of any given gene should have equal chances of being inherited by the progeny. There are a number of reasons why, however, this is not the case, with one of… read more here.

Abstract: Spore killers are meiotic drive elements that can block development of sexual spores in fungi. In the maize ear rot and mycotoxin-producing fungus Fusarium verticillioides, a spore killer called SkK has been mapped to a… read more here.

DOI: 10.1093/molbev/msz160
Abstract: The recent emergence and spread of X-linked segregation distorters - called "Paris" system - in the worldwide species Drosophila simulans has elicited the selection of drive-resistant Y chromosomes. Here, we investigate the evolutionary history of… read more here.

DOI: 10.1098/rsbl.2017.0153
Abstract: Maternally inherited Wolbachia endosymbionts manipulate arthropod reproduction in various ways. In the butterfly Eurema mandarina, a cytoplasmic incompatibility-inducing Wolbachia strain wCI and the associated mtDNA haplotypes are known to originate from the sister species Eurema… read more here.

DOI: 10.1098/rsbl.2022.0352
Abstract: The sex-ratio ‘SR’ X-linked meiotic drive system in stalk-eyed flies destroys all Y-bearing sperm. Unlike other SR systems, drive males do not suffer fertility loss. They have greatly enlarged testes, which compensate for gamete killing.… read more here.

DOI: 10.1098/rspb.2019.1534
Abstract: Most organisms are constantly adapting to pathogens and parasites that exploit their host for their own benefit. Less studied, but perhaps more ubiquitous, are intragenomic parasites or selfish genetic elements. These include transposable elements, selfish… read more here.

Abstract: In two papers published at about the same time almost thirty years ago, Frank (Evolution, 45, 1991a, 262) and Hurst and Pomiankowski (Genetics, 128, 1991, 841) independently suggested that divergence of meiotic drive systems—comprising genes… read more here.

DOI: 10.1186/s12864-021-08170-4
Abstract: Background The nuclear transport machinery is involved in a well-known male meiotic drive system in Drosophila . Fast gene evolution and gene duplications have been major underlying mechanisms in the evolution of meiotic drive systems,… read more here.

DOI: 10.1371/journal.pgen.1009662
Abstract: Segregation Distorter (SD) is a male meiotic drive system in Drosophila melanogaster. Males heterozygous for a selfish SD chromosome rarely transmit the homologous SD+ chromosome. It is well established that distortion results from an interaction… read more here.
