Tony...would you be interested in posting your results to the leopard gecko
forum at kingsnake.com? I know I and MANY others would like to know the
"scoop". I have speculated from the beginning that the Tremper strain was a
T+ albino, but did not know / could not afford to conduct such a test.
Later,
Chris
P.S. T+/T- would explain why the Tremper X Rainwater yields normals.
