Oh no! Not ANOTHER dinker!! Lol

I had 1.2 dark normals and 0.1 dark pinstripe hatch out this season from a pinstripe to a normal (who is darker, but the hatchlings make her look albino lolol). I'm looking for opinions on whether or not I should try to prove this out, or if this is something that happens a lot. Not only are they darker than the rest, they have a "sheen" to them, almost as intense as a rainbow boa's iridescence.

I don't know... but perhaps it could be a darkening clean up gene? You could breed the son back to mama.

I love that dark pin! I'm partial to the dark side though lol so I say to go for it!

Oh those are nice! Would be worth trying, can't hurt. ;)

What really excites me is that ALL of the hatchlings are dark. As of right now (and as far as I know) there is no true dominant gene. Pinstripe and spider don't have a super form, but they don't produce 100% morphs either. I think people refer to them as an "incomplete dominant". Would be soooooo cool to find a true dominant gene! :-D

Wild.

Those babies make me think of an IMG gene sort of...... or maybe something like a chocolate? Mahogany? Sable perhaps? It is weird that all the babies came out dark, for sure I'd be holding back a male to breed back to momma and see where it got me. What if there was a super form?????

You see tons of stuff that lighten everything up, but the dark side is neglected. Except for some of the real recent stuff, GHI and a few others. It would be cool to find one like yours that seems to darken without removing pattern like the GHI.

Keep us updated on these babies as they grow. I'm interested see how their color changes.

The definition of a dominant gene is a gene that the heterozygous and homozygous versions look the same. Dominant genes still have a super but it looks no different than the het version. Don't know why people think a dominant gene would throw all morphs.

This is what we were taught in genetics (years ago)
dominant gene - gene that produces the same phenotype in the organism whether or not its allele identical;
This, to me, means that all offspring would carry one copy of the gene. But I am not a genetics genious.

If it was homozygous dominant, you would yield all visual offspring, het for the trait. A pinstripe, for instance since you have one, if it was heterozygous for pin, bred to another het pin would produce offspring like this:

P | p
P | PP | Pp
p | Pp | pp

Meaning:
~ 25% would be homozygous for pin, and produce only pin offspring when bred to a normal.
~ 50% would be heterozygous for pin, and produce approximately half pins and half normals when bred to a normal.
~ 25% would be normals.

The difference between the dominant above and the incompete dominants you're thinking of with "super" forms is that you would only be able to distinguish a homozygous pin from a heterzygous pin through breeding trials. Incomplete dominants don't quite show the whole of the gene, hence being incomplete.

That all being said, if your breeding yields only darks, then perhaps the original is a homozygous dominant, and there will be no difference in a "super" from a het. But you could have also just gotten awesome odds--all of the percentages are only chances. It's like winning the lottery. :3

If that's the case, and you just got lucky in your odds, then this could very well be a "co-dom" (incomplete dominant) morph. At any rate, keep us updated as this is very exciting. I would keep everything from this breeding in case it turns out to be a new gene. Prove it out, play with it. Then, if you do prove something out, in a few years, sell only the females. Sound weird? If you only sell females, people are limited in the clutches they produce a year and the value will hold longer. ;]

Also, if you have one, TOTALLY put this to a cinnamon or black pastel. I want to SEE that! O__O

Thank you for clearing that up!!
I also hit the odds with 1 male and 3 females, one of which is the pin :-)
My lithium (butter cinnamon) is in with the adult female that produced the dark clutch, I was thinking the same thing you were :gj:
