Dominant Spot first appeared in 1964 [1] Often called simply "Dom Spot", the Dominant Spot is a very common mutation and was the cause of the Piebald Mutations near extinction due to it being easier to breed than Piebald. [1] The Dominant Spot is a spotted-like mutation that effects the whole body and has a pure white belly.
Breeding Note for Dominant Spot
The Dominant Spot gene as well as hiding the Wh gene is a Homozygous Lethal gene. Any pups that have the genotype of "DsDs", basically have inherited 2 copies of the Dominant Spot gene, will die in utero. Whilst it doesn't effect the mother hamster nor the pups because they are not born, it does produce a smaller litter. [2]
