Both breedings have been done before. Butter x Lesser will result in 25% normals, 50% Butter/Lesser, and 25% Blue-eyed Lucy (see here: http://www.worldofballpythons.com/morphs/butter-lesser/), but the Blue-eyed Lucies resulting from this pairing have a tendency to have "bug-eyes", a trait that doesn't seem to harm them, but is undesirable. From what I understand, Butter and Lesser are commonly accepted as the same morph. They seem to be the same gene, just different lines of it. So, identifying the offspring shouldn't be a problem.

As far as Black Pastel x Cinnamon, the results would be 25% normals, 25% Black Pastels, 25% Cinnamons, and 25% 8 Balls (Black pastel cinnamons), which are a solid-colored brownish-black snake that brown out as they age (see here: http://www.worldofballpythons.com/mo...stel-cinnamon/). From what I have heard on these, Black Pastels have black "squiggles" in their alien heads that distinguish them from Cinnamons. This Black Pastel shows prominent squiggles to demonstrate what I mean: http://4.bp.blogspot.com/-lHYW4CLelY...Y/s1600/22.jpg. Comparatively, here is a Cinnamon (note the lack of black inside the alien head shapes): http://i621.photobucket.com/albums/t...280z/Cinny.jpg.

Someone correct me if I'm wrong, please. Oh, and pictures were a result of a google image search and belong to their respective owners.
