wtf genes are ancient meiotic drivers

Meiotic drivers are selfish elements that bias their own transmission into more than half the progeny produced by a driver+/driver- heterozygote. Meiotic drivers are thought to exist for relatively short evolutionary timespans because drivers are generally found in single species, rather than being shared within a clade of close-related organisms. We examine the evolutionary history of wtf meiotic drivers first discovered in the fission yeast Schizosaccharomyces pombe. We identify homologous genes in three other fission yeast species S. octosporus, S. osmophilus, and S. cryophilus, which are estimated to have diverged over 100 million years ago from S. pombe.
