  • a Both strains carry ura3R-HO432 (with nine RFLPs) and ura3-X764; the direct repeats in JW3082 are separated by pUC19 and LEU2 (Cho et al. 1998).

  • b Allelic data are for markers in recipient allele only, from 75 products, including simple gene conversions and complex products. Direct repeat data from Cho et al. (1998) from 86 products, all of which were simple conversions. In both data sets, Ura+ and Ura- products were combined to give unbiased spectra.
