A horrible photo, she was pretty tired of being fussed with. You can see the white-ness in her chest, along her jawline and around her eyes. She's also whiter on her belly, the bottom of her tail and the bottom of her feet.
her hair parted, you can see it's white underneath.
I know she's a Japanese harlequin, but something else seems to be at work. Just wondering what genetically gives her the white base and highlights. As far as I can tell from what I see and what she's produced, her genetics are AaB_C_Ddeje.
