Mating-type switching in fission yeast follows similar rules as in budding yeast, but the underlying mechanisms are entirely different. Whilst the initiating double-strand cut in Saccharomyces cerevisiae requires recombinational repair for survival, the initial damage in Schizosaccharomyces pombe only affects a single strand, which can be sealed by gap repair in situ, whether or not it serves as an imprint for subsequent switching of mating type from an appropriate donor cassette.
