[SKB_Hamsters]

If I understand what you are asking if you breed a normal hair (RxRx) with a carrier (Rxrx) - there a 50% chance of pups carrying the rex gene. This doesn’t mean that 50% of the pups in a litter will be carriers of rex - none may be carrier or they all could be carriers - it all depends on what gene they get from each parent and this is entirely random. However you won’t know who is a carrier of a recessive gene only future breeding will give you answers. The best way to work out inheritance is using a punnet grid (shown in the link I gave you in my first reply).


Unfortunately as I’m not a breeder - I’m not sure how to write genetic codes of hamsters and why each breeder may write them differently. So I can’t help with this sorry.
