The VT gene is the most dominant of all the genes, so you would most likely end up with a high percentage of VT and maybe a few VT's that have the CT look.....you won't get the full finnage though....they would mostly have the droopy looking tail that VT's are known for.
IMO if a person is wanting to breed to get CT, HM etc never use a VT because it will put your betta lines back quite a bit and then VT gene is almost impossible to breed out.
If you're just doing it to see how you do, that's no problem, but you wouldn't get much at all for the fry...maybe $4 or $5 at the most. Also, don't breed any of the babies later on because of the fact they will have the VT gene and you won't get what you're trying to accomplish genetics wise.
