so this would mean the wavy haired ones are just a more subtle or poorer example of a rex and the curly ones are just a better example comparitavly speaking. the shiny ones must just be appearing different as all the others have some degree of rex. makes sense. Also the one dumbo would suggest that the dad is het for dumbo as it is recessive. Breeding rats has much more genetics than i thought. Its actually as rewarding as breeding my snakes.
