More likely than you think. We bred a Lesser to Mojo this year and our results were 1 BEL, 4 normals, and 3 Fires.....she was bred to a Fire in 2011/12. Not a single Mojo or Lesser in the clutch for 2012/13 other than the BEL.
Even less likely is a clutch we had in 2011 of 10 eggs from Pied x het Pied......3 Pieds, all males.....and 6.1 hets. It happens.
BTW, nice looking snakes, especially those banded "normals/yb"?
