I’m not the first person to say this and I’m not the last, but the gene has to have a homozygous form. Unless you’ve bred every single offspring from an eramosa x eramosa pairing and produced multiple clutches from every single one of them (I’m talking at minimum 2-3 clutches with at least 5-6 hatched eggs for every single animal) then there haven’t been enough breeding trials to determine for certain that there is no super. Not to mention, that just goes against how genetics work - an incomplete dominant/dominant gene always has a homozygous form unless, like erie mentioned, it’s lethal and the eggs simply go bad. If this gene still down the line another 20-30 clutches still has no homozygous animals, we’ll have to do some interesting genetic testing because there would be something very abnormal happening there.
That said - i’s a gorgeous gene, and I like it a lot. Excited to see more.
Also, am I reading your original post correctly that you culled any eramosa combo animal that wasn’t use for breeding…?
