Hi Shannon, sorry i missed your call. we'll catch up eventually.
Here's a picture of the male i "proved" to be a hybino (the pale one) alongside the brighter one i tested two years ago and proved to be het/hypo but not homozygous.
I say I "proved" the pale one to be a hybino because test-breeding is a matter of degree: I bred him X two hypo females and got 16 babies, ALL of which are hypos. I THINK the odds of that happening by chance (if he were only a het) are around 1 in 60,000, like throwing heads on a coin 16 times in a row (Shasheena, are you reading this? can you set us straight on the odds?)
So that's 16 data points saying he IS a hybino. But there's always the very remote chance the 17th--or the 117th--could be a non-hypo, proving he's NOT. So i think it's reasonable to say he's proven a hybino, but literally, that can never be said as a result of test breeding. We can DISprove things with absolute certainty, and we can prove an animal is het with absolute certainty, but we can't prove an animal to be homozygous with absolute certainty, not in these circumstances anyway.
So...is yours? Well, my experiment only proves this one pale example is a hybino. It doesn't prove another pale one is. But it gives us some support for the hypothesis presented earlier this year, i.e., pale=hybino. And i guess the hypothesis was actually formulated earlier, since i held back two pale examples in 2004 (i'll post pix of them in this thread).
At any rate, i'll be hoping yours proves to be a hybino.
peace
terry
