Very nice comparison pic!

I've posted my late developer, so you can compare them too.

One question: Are those Sunrise corns a linebred lineage or is it inheritable when you cross different lineages into the original one? I know Sunrise but here in Europe they are not really in demand.

Thank you! And nice animal!! Too bad you sold it.

I believe it's a recessive gene, as Don has them floating around in some of his Amels. I did many project crosses last year, so next season we will find out even more.

Wow, very odd

Chip had this same thing with one of his Scaleless Corns this year. Hatched out looking like a Anery and after a couple sheds, colors came in strong.

BOUT' CORNS !!

You proved that sunrise is either allelic to or the same mutation as kastanie, right?

Yes

I believe Sunrise is Recessive.

Thanks, I found the thread now. The textbook term for the cross you did with the kastanie het amel diffused and the sunrise is "complementation test." Before DNA sequencing, it was the gold standard for testing whether different mutations are in the same gene.

There is a way to distinguish whether they are two different mutations in the same gene (allelic) or whether they are the same mutation, but I'm sure you've already thought of it. A gene can be recessive to wildtype but dominant over its other alleles. If we just assumed that kastanie and sunrise were allelic but not the same exact mutation, since you got babies that looked like mandarins from that cross, it would suggest that kastanie is recessive to wildtype but dominant over sunrise. So if you bred two of those mandarins together you would expect 3/4 of the hatchlings to look mandarin and 1/4 to look sunrise. But of course if the differences between mandarins and sunrise are due to line breeding or the different localities then that would complicate the interpretation. But it'd still be a cool "experiment."

My bet is that they are the same mutation and all of the offspring will look like mandarins, or that there will be a continuum of phenotypes.

Thank you! Definitely gonna do some more with these guys. I did the same breeding again this season.

Due to needing more room for other projects, and waiting on my new Hatchling /Incubation room to be finished, I unfortunately was unable to keep those babies and someone else has the "project animals", but I believe they said that they are looking more like Sunrise than Kastanie now. Since I have more babies coming this season from the same breeding I'm holding on to them. This season I bred the same Kastanie X what is said to be a Christmas Hypo Mahogany. I have a feeling we'll see the same results. I'll post the results of that breeding here when the time comes.

Cool. When you say they are looking more like sunrise than kastanie, do you mean that those mandarin-looking hatchlings grew to look more like sunrise than mandarin?

Yes that's correct.
