From my research you will end up with f1 mischlings, so you will end up with mostly normal looking crs and/or cbs that carry the taiwan bee genes. you have a VERY slight chance of taiwan bees popping up, then the mischlings need to be bred back with a taiwan bee for increased chances of taiwan bee offspring. like i said this is all from research and not from first hand experience, so maybe someone can chime in with first hand experience.
