Same Strain Parents From Different Breeders

In front its the Cocopopo from Bulk seeds and in back is the Chocolate Haze from Royal Seeds.  Both have the same strain parents OG Chocolate Thai, and Cannalope Haze. The OG Chocolate Thai could be from anywhere but the Cannalope Haze should have come from DNA genetics, unless some other breeder has borrowed the name, that would never happen. Anyway, they couldn't be more different even if one was an auto. Its interesting to me  when 1 +1 =3 or 17 and that is kind of the way this works it seems
