Good questions! I hope you get good answers. Where is Ralphy boy when you need him?
I’ve had a hard time with this one to. Looked into it awhile back and eventually gave up on it for a while.
What I do remember is that the original Platinum produced off spring that looked like a lesser version of the dad, so Ralph called them lesser and he theorized that the dad had and extra hidden gene that made the dad more hypo looking than the lesser offspring. The lesser gene is co-dom. The “hidden gene” is ……simple recessive?
Morph Market list Het Daddy as the heterozygous co-dom form of the Daddy.
Morph Market list Platty Daddy as lesser and het daddy, 2 different co-dom’s that do not produce BEL.
According to Ralph, the only way to produce Platties is: “Platties are still only being produced from breeding a Lesser that is sired by Platty Daddy to a normal looking that is sired by Platty Daddy…or Platty Daddy x normal sib or Lesser.”
That sounds recessive to me? Yah, I’m confused. Did the recessive turn out to be hypo?
Here is a link to Ralphs page on Platinum. Unfortunately, it hasn’t been updated in a while. Maybe it will help you. Good luck.
