If the platty daddy special gene is located on the X chromosome, Ralphs results make sense. It would also mean that it's a recessive gene(or genes). Think bout it this way.. Large X's will indicate normal genes, little x's will be recessive
Pladdy Daddy X Normal Mother
xy * XX
YX, xX are your two possible out comes, neither would express the trait, but if you bread platty daddy back to one of the normal looking off spring you'd get
xy * xX
and you'd get
yx, xx, Xy, Xx, so you'd see .25 percent male platty Daddy, .25 percent female platty daddys and then normal males and female het platty daddys.
Does this make sense? It it's a sex-linked trait you'd get the results he's seeing. I don't know a whole lot about it but I figured this might be a possible explanation.
edit: It may not be officially XY for reptiles, I'm trying to find out what the sex chromosomes are called, I'll add it if I have any luck.
I emailed this to ralph to see what he thinks. Hopefully this is right and we can make many more of those gorgeous snakes.
