Since spore killers are also dominant suppressors of meiotic silencing, it is very interesting results that this suppressor is not able to suppress meiotic silencing of unpairing at rsk locus due to deletion. This suggests that suppressor of meiotic silencing in spore killer is a weak suppressor like the one identified in the wild isolated strain CMG (https://www.ncbi.nlm.nih.gov/pubmed/21295150). It might be that nature selects only weak suppressor of meiotic silencing. It is also possible that un-pairing at the rsk locus due to deletion of resistant allele causes pairing at the suppressor locus in a heterozygous cross due to the presence of several inversions that surround Sk allele. It could be tested easily by making a cross, which is heterozygous for GFP also, by putting an ectopic copy of GFP in one of the parental strain.
