An example punnett square for a cross of an XxYyZz snail (dark striped purple) to another XxYyZz snail (also dark striped purple):
|__XYZ___|__XYz___|__Xyz___|__xyz___|__xyZ___|__xYZ___|__XyZ___|__xYz___
XYZ | XXYYZZ | XXYYZz | XXYyZz | XxYyZz | XxYyZZ | XxYYZZ | XXYyZZ | XxYYZz |
XYz | XXYYZz | XXYYzz | XXYyzz | XxYyzz | XxYyZz | XxYYZz | XXYyZz | XxYYzz |
Xyz | XXYyZz | XXYyzz | XXyyzz | Xxyyzz | XxyyZz | XxYyZz | XXyyZz | XxYyzz |
xyz | XxYyZz | XxYyzz | Xxyyzz | xxyyzz | xxyyZz | xxYyZz | XxyyZz | xxYyzz |
xyZ | XxYyZZ | XxYyZz | XxyyZz | xxyyZz | xxyyZZ | xxYyZZ | XxyyZZ | xxYyZz |
xYZ | XxYYZZ | XxYYZz | XxYyZz | xxYyZz | xxYyZZ | xxYYZZ | XxYyZZ | xxYyZz |
XyZ | XXYyZZ | XXYyZz | XXYyZz | XxyyZz | XxyyZz | XxYyZZ | XXyyZZ | XxYyZz |
xYz | XxYYZz | XxYYzz | XxYyzz | xxYyzz | xxYyZz | xxYYZz | XxYyZz | xxYYzz |

If you would like to know what colors can result from certain color crosses of snails, look at the downloads secion of this site and try the Color Inheritance program. It will give a list of possible color outcomes for any combination of yellow-brown colors, purple colors, or olive colors, provided that the parents are in the same color "group" (i.e. olive with olive, purple with purple, etc.). Burgundies are not yet understood well enough to include in the program.
For more information on punnett squares or how to know what types of babies two given snails will have, feel free to e-mail me at DonyaVQ@netscape.net. Please contact me if you have any genetics questions/comments or other related questions/comments as well.
