Herbal, thanks, I'm not entirely convinced that these types of plants do contain 3 helixs on their dna chain. It could also be the result of a single gene doubling itself (or some type of typical mutation resulting in trifoliar tendencies) within one of the chromosomes, which takes place all the time, having varying effects. Until someone actually maps the genome of one of these, (and I don't have those resources), it's all guess work as to what's going on at that level. Although I would have though myself that a true polyploid would pass that trait onto all of it's offspring. Whereas when breeding trifoliar plants, the offspring tend to show traits which would be more relevant to standard hiredity theories, such as dominant and recessive traits. With the trifoliar pheno being a recessive trait. But like I said it's all theory at this point.

Hi Hal, depends on how you grow, I get more growing sites from topping bifoliars repeatedly. They just look nice Outdoorgrower, trying. Although I'd rather it was an option rather than in half of everything.Herbal, thanks, I'm not entirely convinced that these types of plants do contain 3 helixs on their dna chain.
