morph VS. temperament

I personally believe they do. With any species. Key word genetics. Doesn have to do with individual colors for say. But considering the mom or pa who carried the nasty disposition. Will never be forgotten. Maybe dormet for some generations. But that one baby will eventually re introduce it. IMO pastels are never nasty. But jumpy. Depending on how well he was cared for will lable how aggressive he'll actually get. My personal experience was with burm. Iv noticed granite burm to be nasty. Iv had 4 granites and everyone gave me a scar. My dealers burm was nastey. I ask was it a normal. Na. Go figure. Granite. I had a talk with Ben rodger about it. He said he has his sweetest burms. Which happen to be a green and granite.
But he agreed. Every granite he messed with mostly. Was mean. Even when I went to buy some leopard geckos. Guy had a small granite. Bit the crap outta me lol. So i do believe its not morphs itlsef. Just a narly gene in the heritage. Just happened this one was a morph.

All of mine are calm as can be except one (pastel yellowbelly) and she is extremely aggressive lol.. You cannot hold her without bloodshed..

I have a pastave male who hisses and strikes every time I pick him up but I have a pastel female who is as sweet as sugar. Both are adults he is approx 900gr and she is just over 1500gr.
