Hey retic experts...can someone tell me what actually makes a tiger morph? The reason I ask is that the lateral white patches on my SD are quite elongated compared to my other retics. This seems to be a common visual trait in the tigers I see. However, the back pattern doesn't look anything like what I understand a "tiger" to be. Can someone give criteria or some consistent finding on this? Here's a pic of my SD (blurry, sorry. He wouldn't stop moving). I'm guessing it's just what this guy looks like and nothing more.
