In mammals exist the "piebald" gene giving them the "harlequin" phenotype.
It's a combination of 2 genes that causes this effect.
Something remarkable is the phenotype changes when these 2 genes are hetero- or homozygote.
HH as in MMHH or mmHH or MmHH is lethal, so not exists.
This have similarity effects as on the Silkie Platenbont (MmHh and MMHh) also the" ivory" grey shade (Mmhh).
Here is an example in dogs to compare with the Moroseta pezzata.
