Winter Whites have been hybridised with Campbells hamsters. Unless the WW are from a registered NHC breeder it is highly likely that they have been hybridised at some point in their family tree. If the hamsters were from a pet shop then they will be hybrids and shouldn't really be bred from.

Hybrids can have health problems such as being prone to diabetes and neurological issues. There is also the question of whether it is ethical to support the breeding of hybrids rather than trying to breed the pure species
