I don't yet have an opinion on Howletts as I've not had the chance to visit, but just wanted to find out more about the Bengal tiger (insert quotes if desired) captive population. I'd never thought about most Bengals being of hybrid origin - some I knew were (at Paradise Wildlife Park, for example). What is the genetic makeup like of such a population, are they being phased out for breeding, and what of white Bengal tigers - are they not genetically pure P. t. tigris? Thanks!
