Resolution of recombination intermediates generated during yeast mating type switching

Abstract
Interchromosomal gene conversion between alleles in yeast [Saccharomyces cerevisiae] is frequently associated with the recombination of flanking genetic markers. Although this also holds true for gene conversion between 2 alleles of the yeast mating-type (MAT) locus, initiated by the homothallic switching system, no evidence was found that cross-over ever accompanies gene conversion between the non-allelic HMR and MAT genes when initiated by this same homothallic switching system.
