I have no idea where the red with horizontal tiger stripes comes from...
Seems it is, for the most part, very prevalent in all the feral populations where I hunted or follow the pursuits of others in many locations. I see mainly red with stripes or black piglets... Sometimes with the hampshire type belts. I've never seen a single pie bald (polky dotts
) piglet... I have seen many captured red stripes raised and never noticed their transformation. I have never raised a "weiner" feral myself.
