Polish Chicken Plumage Genetics

[sylviethecochin]

Ah right Thankyou for correcting me!

As I say, I am definitely still learning with genetics...so many colours and such that can make other colours and so on.

All of my first generation chicks are one solid colour they don't have any leakage or strange colours. The whites are all white, the partridges are all partridge etc.

Of course they aren't genetically pure, but their physical colours are. I hope that makes sense?

Although, I believe my white male originated from partridge so maybe that's why he's produces nice partridges too? I'm not sure but the partridge chicks are beautiful!

I was meaning that if I was to breed those first generation chicks, there is no guarantee that you wouldn't get leakage on the second generation (their offspring). The chance of leakage in second (and further generations) is high. Except my whites which always have bred 100% white for me.

Although I thought if I was to breed one of my white x partridge chicks to a pure partridge that doesn't have a white gene, I would get partridge chicks that also just carry the recessive white gen with no leakage.

I can't have any say on the wheaten colours or duckwing as I've never bred them myself.

If I ever have any questions about genetics etc you seem really knowledgeable! If you don't mind I may ask again in the future.

Ask nicalandia instead. I'm not quite an amateur, anymore, but I certainly wouldn't call myself an expert.

And recessive white never shows leakage. There are either two copies and the bird is completely snow white, or there's one copy and it has no effect.

Oh yes they're very good with genetics too (having received some previous help from them too).

Still Thankyou for helping though!

I never knew that about recessive white but I'm quite pleased about it. I'm guessing it's better to have recessive white rather than dominant white? I'm guessing my boy has the recessive from what I've seen in his chicks.

Recessive white is the only gene (of which I know) where two copies of it make the bird completely white no matter what other genetics are in play.

Dominant white, on the other hand, just whites out any of the black patches on the bird. Two copies means that the white-out is complete; one copy means there might be a few black patches.

So if your white boy was dominant white and produced partridges, a few of them should have had white where the black is. Silkies are almost always recessive white.

For the laced birds you can get a classic sex-link with red roo over silver hen. If they’re switched it’ll be a tossup. Doing so too long, however, may cause leakage.
Red and buff in either gender can work - some have used it to improve the contrast with the buff against white lace. But I’m led to believe that the red/golden is a different gene than the buff.
Lastly, buff laced is really white laced buff; white being dominant white, so crossing it/roo with a black laced silver hen will give 50% female gold (1/2 black or white lacing) and 50%males silver (1/2 black or white lacing). This combo gives an appearance of an all-white bird.
Although I would use dominant and recessive white to create a white bird as each one independently affects PHEOmelanin (red) and EUmelanin (black).
