Discussing details of mottled chicken genetics

[MysteryChicken]

This hen would work perfectly. She has really nice mottling. Though she isn’t a pure Japanese bantam, due to her pink legs.

I thought she just had shank color diluter genes.

I don’t have advanced knowledge of leg color genetics, but I looked at some blue mottled Japanese bantams and they all have yellow legs. @Amer might know more than me?

I found a couple pictures of Japanese Bantams with pink/white legs.

Are you sure they aren’t a different breed? Some images like that showed up, but they were pretty obviously seramas.

I gotta go feed the birds now.

Huh, that’s interesting. It looks like the first is a poor quality hatchery bird, and the second is a project color, which was probably crossed with another breed (like serama or OEGB). Still, it’s possible. I didn’t think any Japanese bantams had those genes.

He is a nice OEGB mix, but if it’s possible that he carries mottling, then the test wouldn’t work. That’s because his offspring could be mottled, whether or not the d’uccle carries a dominant mottling gene.

Sorry but mottling (mo) is a single recessive gene.

We all know that, but MysteryChicken has a chicken with something that looks like mottling, that is apparently behaving like a dominant gene.

So we've been discussing how to set up one or more test-matings to figure out what is going on. RoostersAreAwesome was pointing out that a bird that might carry mottling (but no-one is sure either way) cannot be used in this test.

I agree with you. I think the birds pictured on the first page of this thread have leakage, not mottling. It’s MysteryChicken’s theory that a dominant mottling gene exists. I’m discussing the best way to test whether this is true or not, even though I personally don’t believe it, I’m open to experimentation.
