The breeding was female Pastel to male Ivory and male Super Pastel Lesser Het Hypo. When an Ivory is bred to a Pastel, the two possible outcomes are Yellowbelly and Pastel Yellowbelly, which leaves the Super Pastel Lesser as the sire for the Pastel.
I originally thought that the SPL would get the job done because he locked 7 times and the Ivory only locked twice. The Ivory is a 2010 though whereas the SPL is a 2012. Maybe age played a factor. I also had 2 slugs in the clutch and i blame the SPL for them lol.
