Haha, no. He actually thought this rat was literally half dumbo. The mother was a dumbo and he said this female from her litter was different from the others. The ears were bigger, the face was wider, and the fur was softer, all qualities of a dumbo, so therefore, the rat was half dumbo. I told my friend that that was absolute BS (in a nice way of course) and that her rat simply carried the dumbo gene. There would be no physical display of that gene unless she was homozygous for it.
