Reduced spore viability in crosses homozygous for the rad22 deletion. The progeny of crosses involving wild-type parents (1-11 and 3-99), rad22Δ parents (GO123 and GO126), rti1Δ parents (GO179 and GO181), rad22Δ rti1Δ parents (GO228 and GO243), rad22Δ rti1Δ rec12-Y98F parents (GO247 and GO248), and finally rec12-Y98F parents (KLY144 and GO244) were tested. For details, see supplemental Table A3. The error bars represent the standard error of the mean. A 2-fold reduction of spore viability was observed for rad22Δ, while the rad22Δ rti1Δ double mutant displayed a 20-fold reduction.
