Not necessarily dude, the first pintos had stripes like this one from a German breeder.
Personally(& this is strictly my opinion cause this is a widely debated topic) I think TaiTibee is a invalid name as Tibee is a tiger crossed with a Bee shrimp & a TaiTibee is supposed to be a Tibee crossed with a Taiwan bee, which is essentially an F2 Tibee cause a Taiwan bee is a Bee shrimp just a different variant, Bee shrimp can be CRS, CBS, Golden Bees, Snow Whites or any of the Taiwan Bees. For this reason I don't actually get why it has been given a different name, it would be like calling an F2 Mischling a TaiMischling, just doesn't make sense to me #justsayin, lol
