If different types of cells looked different, we would have zebra stripes. I think only geneticly female people would though, for the same reason only geneticly female cats can be calico.

CORRECTION: This happens in both sexes. The difference between cells comes from whether each cell uses one parent's X chromosome or the other parent's. This decision happens when there's just 100 or so cells, so the different cells spread like rock layers as they divide, leaving stripes of them covering the body.

Ok. Show me that.
