Is "Rumpless" a dominant or recessive trait?

[WiseChicks]

I have Belgian d'Grubbes, which are rumpless Belgian 'Anvers.

I am wondering what I'd get if I bred my d'Grubbe to a d'Anvers.

Any info would be greatly appreciated.

Rumpless Rp is Dominant, wildtype allele is the recessive rp+.

ok, any way to know what type of gene the d'Grubbe carry, or is it simply, breed them with some d'Anvers and see what I get?

Most likely dominant. You would know after hatching the crosses.. if any of them turn out rumpless, it is proof of the dominant form.

Grubbe are dominant rumpless.

 

[nzpouter]

is it lethal in homozygous?

 

[Mahonri]

I thought that "tufts" in Araucanas carried the lethal gene?

 

[wilds of pa]

Rp is not lethal, tufted can be by double dosing it..

Oh, Thank you!!

I would be so sad to see my little group of d'Grubbe go away. Now I'm on the hunt for d'Anvers!
