Yes they are. The 2 species mixed (lions and tigers) was merely an example I was giving. It's probably the most exempting example out of any I could give so I admit it's not that bad since they are a compatible species. Just trying to give an example. Anything that involves extracting DNA is what isn't right. Lions and tigers can breed naturally and it doesn't cause a problem. It's when you extract the DNA from an animal to un-naturally breed it in my opinion that it's wrong.Ligers are beautiful animals which won't be here if it wasn't for cross breeding.
Actually im in complete agreement with you when saving a species is the reason. In that case the species must survive somehow and it's the only way. They are currently cloning sheep. I can't exactly remember what it was for I think to harvest apart of them. Can't remember if it's the organs or what but what is your thoughts on cloning?I think it's not right to deform a life on purpose but us, humans beigns are used to do that kind of stuff, even if we are against it, someone somewhere is doing it.
Unless there IS a good chance to maintain a species (in danger of extinction). I'm just trying to justify..
