Albino and Piebald

[Jay_Bunny]

I've read that the piebald trait and albino trait are recessive. My question is, are they co-dom with each other. I saw a picture of one of Ralph Davis's albino pieds and I was wondering how that was acheived.

Recessive traits are always recessive.

The way you get something like an albino pied would be to breed an albino to a pied...and all the babies would be HET for each trait...or "double het(DH) for albino/pied."

Then you take two DH animals and breed them together....and pray to the morph gods (or Kevin @ NERD ) that you hit on the 1 in 16 odds of hatching out an albino pied.

Ok. Now I understand how that works. Thanks!

(Albino pieds are sooooo hot. They are unbelievable.)

okay to sort of hijack this thread, although its still related to pied .. and to get a cinnamon pied. You would have to breed a pied to a cinnamon or could you breed a het pied to a cinnamon and hopefully get a cinny pied out of the clutch (Im sure with much praying to the morph gods). am I correct on this or..?

I am interested to know about the cinnamon X pied crossing as well.

Oh and what will the hets of the albino x pied crossing look like. Since the albino lacks the trait for a normal and so does the pied, do they look normal, or am I totally wrong about the pied and albino lacking the normal trait?

Ok....to get a cinny-pied.... You'd need to breed a pied to a cinny and get some cinnies that are het for pied. Then breed one of those back to the pied (or another het pied) for a chance to hatch a cinny-pied.


As for the outcome of breeding DH albino pieds together...a clutch might include any of the following babies:

--Normals that are possible DH albino/pied (meaning it could be het for either or both)
--Albinos that are possible het pieds
--Pieds that are possible het albinos
--Albino Pieds

After reading this again, I think I answered the wrong question in my previous post. So lemme try again...

Het albinos look normal.....and het pieds look normal.....therefore, DH albino/pieds will also look normal.

In order for an animal to NOT look normal (in this example) it must carry both pairs of the recessive gene in question. Each parent gives the baby ONE of the genes that make up that pair. If you breed an albino to a pied...the albino passes ONE albino gene and the pied passes a normal gene (for that slot...or allele)....and the pied passes ONE pied gene while the albino passes one normal gene for that slot.

Therefore, the babies look normal, but each carry one copy of the albino gene and one copy of the pied gene.

Is Cinnamon Co-Dom? I think it is but I'm not sure. If it is, then all offspring of a cinnamon X pied crossing would show cinnamon but be heterozygous for pied right? So as far as possible offspring for the het offspring x pied crossing it would be something like this?

- Cinnamon het for pied
- Normals het for both or either
- Pied het for cinnamon
- Cinnamon Pied

[Jay_Bunny]

Ok, so second generation would all look normal, but carry albino or pied, or both, correct? And then third generation, you have the potential of producing pieds het for albino, albinos het for pied, normals het for either or both, and albino pieds?

Cinnies are co-dom...so there is no such thing as "het for cinny."


A cinny x pied could potentially yield cinnies AND normal looking babies...but all of them would be het pied.
