I'm not sure if it's classified as a dominant or co-dominant mutation, but it mostly messes with pattern and can be more subtle or very pronounced. I have been trying to look up the same morphs with and without trick to try to get a better sense of it. For the pinstripe (named Chicory) I wonder because he has a lot more pattern than other hypo pins I see, and the pattern in the alien heads is expanded and more of an outline. I wonder for Barley, the black pastel because her pattern is more twisted and busy than I have typically seen.
