With hamsters, sometimes the only way to truly know what other colours they carry is to mate them with a hamster who is a different colour. To illustrate my point, I mated my black girl Nessie to a cinnamon boy Gadwin. Cinnamon is recessive, so is black. If I get doves, it means that boy parents carry each others colours. i.e. Gadwin carries black and Nessie carries cinnamon as you need two of both of these genes in one hamster to produce this colour.
I was expecting goldens but suspecting cinnamons as Nessies dad Dougal had thrown some funny honey babies before. Lo and behold I got this:-
Hmmm, very orange for a golden? I jest, this is a cinnamon girl. This mating proves Nessie does carry cinnamon. Sometimes pedigrees can’t tell you everything and this is why we test mate to prove purity in lines that shouldn’t have anything in them. Recessives can carry a loooong way 😉
