Even without ATP-analog, hhp1-as hhp2∆ mutant has strongly reduced meiotic recombination but only weakly reduced viable spore yield.

a Data are cM, calculated from the observed recombinant fraction using Haldane’s equation.b Data are the number of Ade+ recombinants per million viable spores.c Data, from (n) crosses, are the mean viable spore yield per viable cell of the less numerous parent in each cross relative to that of hhp1+ hhp2+ without analog (4.9).d Data are from [63].e Not determined.f Data are from [64].Even without ATP-analog, hhp1-as hhp2∆ mutant has strongly reduced meiotic recombination but only weakly reduced viable spore yield.
