Anyone know what types of chicks result from tan-striped/tan-striped couplings? Are they a mixture of white-striped and tan-striped? Or are they all tan-strip

Anyone know what types of chicks result from tan-striped/tan-striped couplings? Are they a mixture of white-striped and tan-striped? Or are they all tan-striped? And likewise for white-stripe/white-stripe couplings? The article says the single-striped couplings are rare in nature, but I'm wondering none-the-less.
