four gene mutations affecting recombination rad50 , rad52 , rem1 and spo11 have been extensively examined in several laboratories and illustrate the information that can be obtained by characterization of double mutant strains , detailed genotypic analysis of recombinants , and studies of meiotic recombination in cells in which the reductional division of meiosis has been bypassed by the spo13 mutation .
