I've got my first gaggling of bollocks right now, so i'm no expert, but i thought you could backcross to cancel out traits and come out with a steady pheno? Not to mention how can exodus cheese have different pheno's? Exodus cheese is not a strain, it's a phenotype is it not, so any variation on the pheno is not therefore exodus cheese?
The argument that it's different because it's a new mother, not a clone of a clone, well that's just his opinion and a biased one at that quite naturally, so i'll not pay heed to that.
