The following genes of the fission yeast Schizosaccharomyces pombe have been mapped by tetrad analysis--chromosome arm I-L: mfm2, rad24, rad25; I-R: abc1, fus1, mfm1; II-L: mfm3; II-R: mam1, rad13. A hot-spot of meiotic recombination although not quite so active as suggested by previous maps, may be located between rad25 and aro5 on I-L.
