CO:NCO ratio of markers flanking gene conversion events on chromosomes VII and VIII.

Tetrads containing a gene conversion at the MET13 or THR1 loci were analyzed in wild-type and pch2Δ mutants in the NHY background. The markers flanking the gene conversion event were scored as CO (TT or NPD) or NCO (PD) and the CO:NCO ratio was calculated at each site. The wild-type and pch2Δ CO and NCO numbers were compared using a G-test and the p values are shown.
