Simons,
I know what you mean, but they don’t look like Standard Hypos to me.
It seems as if there are two hypos that are being called an “Ultra” or at least two different looks within the Ultras. Kat’s Ultra and Jason’s Ultras look quite different. I know Kat’s is a Motley, but I have seen other Ultras that look like Kat’s as well that are not Motley. Strawberries have been called Ultras in the past too.
I have seen other Ultra Hypos from Roylance and Falcon that look like Jason’s as well. It would be interesting to breed the two difference looking Ultras together and make sure they are the same hypo gene. Perhaps, difference localities are giving them their differences in appearance, but the differences are dramatic. Maybe it is just that Kat’s is a Motley, and the lightening effect of the Motley is causing the dramatic difference.
