im breeding rats for snake food and have noticed my litter has a bunch of different hair types not just color variation. A long with being every colour imaginable(in a rat) the is also super shiny babyX2 normalX2 rough furredX9 and curlyish furX4. The parents all seem to have normal fur so i was wondering what the genetics was on this. I thought curly fur ras like a visual het for hairless but now i dont get it as all parents look normal. Pictures tomorrow hopefully. They are 2 weeks old.
