We have observed maternal transmission ratio distortion (TRD) in favor of DDK alleles at the Ovum mutant (Om) locus on mouse chromosome I I among the offspring of (C57BL/6 X DDK) F, females and C57BL/6 males. Although significant lethality occurs in this backcross (similar to ...
Population dynamics of transposable elements: Copy number regulation and species invasion requirements
Tags: Gene drive synthetic, Selfish genetic elementsStruchiner, CJK, M. G.; Ribeiro, J. M. C., Journal of Biological Systems, 13:455-475. 2005.
A deterministic population dynamics model of the spread of transposable elements (TE) in sexually reproducing populations is presented. The population is modeled by a three-parameter equation describing host reproductive capacity, population size and the strength of the density ...
Evidence of susceptibility and resistance to cryptic X-linked meiotic drive in natural populations of Drosophila melanogaster
Tags: Evolution, Gene drive mechanisms, Other arthropods, Transmission distortionReed, FAR, R. G.; Aquadro, C. F., Evolution, 59:1280-1291. 2005.
There is mounting evidence consistent with a general role of positive selection acting on the Drosophila melanogaster X-chromosome. However, this positive selection need not necessarily arise from forces that are adaptive to the organism. Nonadaptive meiotic drive may exist on ...
Transposable element insertion location bias and the dynamics of gene drive in mosquito populations
Tags: Gene drive mechanisms, Gene drive syntheticRasgon, JLG, F., Insect Molecular Biology, 14:493-500. 2005.
Some vector-borne disease control strategies using transgenic mosquitoes require transgene spread to high frequency in populations. Transposable elements (TEs) are DNA sequences that replicate and transpose within the genomes of other organisms and may therefore be represented in ...
Segregation distortion in hybrids between the Bogota and USA subspecies of Drosophila pseudoobscura
Tags: Ecology, Evolution, Gene drive mechanisms, Transmission distortionOrr, HAI, S., Genetics, 169:671-682. 2005.
We show that, contrary to claims in the literature, "sterile" males resulting from the cross of the Bogota and USA subspecies of Drosophila pseudoobscura are weakly fertile. Surprisingly, these hybrid males produce almost all daughters when crossed to females of any genotype ...
Degeneration and domestication of a selfish gene in yeast: Molecular evolution versus site-directed mutagenesis

VDE is a homing endonuclease gene in yeasts with an unusual evolutionary history including horizontal transmission, degeneration, and domestication into the mating-type switching locus HO. We investigate here the effects of these features on its molecular evolution. In addition, ...
Meiotic drive at the Om locus in wild-derived inbred mouse strains
Tags: Ecology, Other mammals, Transmission distortionKim, KT, S.; Howard, I. B.; Bell, T. A.; Doherty, H. E.; Ideraabdullah, F.; Detwiler, D. A.; De Villena, F. P. M., Biological Journal of the Linnean Society, 84:487-492. 2005.
Meiotic drive is an evolutionary force in which natural selection is uncoupled from organismal fitness. Recently, it has been proposed that meiotic drive and genetic drift represent major forces in the evolution of the mammalian karyotype. Meiotic drive involves two types of ...
Genetic linkage between a sexually selected trait and X chromosome meiotic drive
Tags: Evolution, Other arthropods, X chromosomeJohns, PMW, L. L.; Wilkinson, G. S., Proceedings of the Royal Society B-Biological Sciences, 272:2097-2103. 2005.
Previous studies on the stalk-eyed fly, Cyrtodiopsis dalmanni, have shown that males with long eye-stalks win contests and are preferred by females, and artificial selection on male relative eye span alters brood sex-ratios. Subsequent theory proposes that X-linked meiotic drive ...
Gene drive systems in mosquitoes: rules of the road
Tags: Gene drive synthetic, Other arthropods, Risk and safetyJames, AA, Trends in Parasitology, 21:64-67. 2005.
Population replacement strategies for controlling transmission of mosquito-borne diseases call for the introgression of antipathogen effector genes into vector populations. It is anticipated that these genes, if present at high enough frequencies, will impede transmission of the ...

Intraparental gamete competition provides a selective advantage for the development of hybrid sterility via meiotic drive
Adams, CS, Evolution, 59:1229-1236. 2005.Hybrid sterility can have evolutionary significance and varies substantially by taxon, but few models attempt to predict or explain this variability. Hybrid sterility is commonly observed and develops early in isolation, at odds with straightforward models that predict it would ...
