I have incrossed/backcrossed the ChemD and 4 clone, initially with one of Rez's CDIBL males, for 5 generations and what you get is very much like the two sisters. I don't see why anyone would use a S1 as a father, when you can easily breed something that resembles the original Chemline, narrowed down even, with healthy males.
How hard can it be if you are a professional commercial breeder ?
An S1 male is genetically bad shit. Why degrade the gene pool of the Chems
so cal seeds is saying they have a REAL male chem D not and s1 or anything else but a solid pure chem d male.
