Meiotic drive in female mice: An essayRuvinsky, A, Mammalian Genome, 6:315-320. 1995.
Since the rediscovery of Mendel's laws, geneticists have accumulated various examples in which equal meiotic segregation in heterozygotes is violated. However, only a few natural meiotic drive systems have been characterized in detail and the majority of these are sex chromosome ... |

Ascoycete spore killers: Chromosomal elements that distort genetic ratios among the products of meiosisRaju, NB, Mycologia, 86:461-473. 1994.
Spore killers (Sk), studied most extensively in Neurospora, are also known in Podospora, Gibberella and Cochliobolus. Spore killers are no doubt present in natural populations of other fungi. Criteria are outlined here for recognizing their presence and distinguishing them from ... |

Selfish DNA as method of pest controlHastings, IM, Philosophical Transactions of the Royal Society B-Biological Sciences, 344:313-324. 1994.
The inheritance of most genes is tightly controlled, governed by the rules of mendelian inheritance if nuclear or uniparental inheritance if cytoplasmic. A few notable genes and cytoplasmic genomes have escaped this regulation. Such genes may spread by increasing their own rate ... |

The peculiar journey of a selfish chromosome: Mouse t-haplotypes and meiotic driveSilver, LM, Trends in Genetics, 9:250-254. 1993.
Mouse t haplotypes are descendents of a variant form of chromosome 17 that evolved the ability to propagate itself at the expense of the wild-type homolog from heterozygous +/t males. Although once enigmatic, these widespread selfish chromosomes have revealed many of their ... |

Cheaters sometimes prosper: Distortion of Mendelian segregation by meiotic driveLyttle, TW, Trends in Genetics, 9:205-210. 1993.
Two of Mendel's three laws were quickly discarded as information on the organization and transmission of genes accumulated at the beginning of this century, but bis law of segregation has shown remarkable staying power. In fact, within most of population genetic theory for sexual ... |

Meiotic drive in Neurospora and other fungiTurner, BCP, D. D., American Naturalist, 137:416-429. 1991.
When a gene complex called Spore killer is heterozygous, ascospores representing two of the four products of each meiosis are killed. Only those that receive the killer complex survive. This article reviews what is known of the mode of action of the Neurospora Spore killers, ... |

Extraordinary sex ratiosW. D. Hamilton, Science, 156:477-488. 1967.
The two sexes are usually produced in approximately equal numbers. Fisher (1) was the first to explain why, under natural selection, this should be so, irrespective of the particular mechanism of sex determination. His rather tersely expressed argument has been clarified by ... |

Aanalysis of case of meiotic drive in Drosophila melanogasterHanks, GD, Genetics, 50:123-130. 1964.
IN the past ten years there has been a renewed interest in the abnormal recovery of chromosomes after meiosis; see for example DUNN (1953); NOVITSKI and SANDLER (1957) ; SANDLER and NOVITSKI ( 1957) ; LINDSLEY and SANDLER (1958); NOVITSKI and HANKS (1961); and MAGUIRE (1963). ... |
