Do paint silkies get their spots over time?

[nicalandia]

Paint is a co dominant gene expression. You breed a white silkie (WW) to a black silkie (BB) and get paint chicks (WB). If you breed the paint chicks back together you will only have a 50-50 chance of the babies being paint colored. Genetics can be confusing but I hope this helps a little.

Paint is not a gene so by definition is neither a co-dominant or recessive gene, it's the name for a phenotype which is based on an Extended Black background(E/E) that is diluted by heterozygous dominant white(I/i+) the phenotype called paint is another name for the Erminette pattern, The paint pattern does not breed true, if you breed paint to paint you will hatch 50% paint, 25% all black and 25% all white

Thanks! I was trying to explain the Cliffnotes version of the gene expression. I thought that terms like heterozygous or extended black might make things a little too confusing. I do believe the paint coloration is an expression of co-dominance, though. Come to think of it, it could also be incomplete dominance, since you mentioned the term "dilute".

Like I said there isn't a paint gene. And usually breeding a black to a white silkie won't give you paints.
There's two different kinds of whites. Recessive white is what silkies are. With them it takes a white gene from both parents to produce a white chick. If the offspring only gets one copy it will be black or what have you and carry one copy of white sight unseen.
The other white gene is dominate white. That is the white involved in paints.dominate white is dominate so it only takes one copy to show. With one copy though it doesn't make a completely white bird. It lets some color show up in specks or splotches. That's what a paint is. Just one copy of dominate white.
That is also why they won't breed true. Since each paint has one copy of DW and one copy of no DW they have the option of passing DW to their offspring but the same chance of not passing it on.
50% of the offspring will end up with one copy. 25% will get no copy from either parent and not have white at all. The other 25% will get a copy from both parents and with two copies be completely white so no spots.
If you get one with two copies and breed it with a black you will get 100% paints since the offspring can only get one copy from the white parent and not a copy from the black parent.
Make sense?
I know paints are coming in other colors now. I've seen paints, blue paints and hear of people using blacks with leakage.
Another interesting thing about DW is that it doesn't do much for covering gold/red. There's other breeders using it on partridge type silkies so the red on wing bars and breast etc. shows so you get a white bird with some red showing.
Search red pyle silkie. I think I may be interesting if someone would combine the pyle with blue paints then you would have red, white and blue silkies. But that's a whole new subject.

Thank you so much for explaining it so clearly! Genetics can be so confusing for me sometimes.

I understand your point, but I am really against oversimplification,

Dominant white is incompletely dominant, Splash on the other hand is an example of co-dominance

Everyone has to start somewhere when learning genetics. I thought that once the concept of co-dominance was explained, the addition of other concepts such as heterozygous and dominant vs recessive genes would sound a little less like Greek, LOL

I would dearly like to see some splash Silkie Punnet squares.

I had it backwards, Dominant White is Co-dominant, the Erminette pattern in chicken is used as an example of the co*dominance inheritance, Source: http://lhsblogs.typepad.com/files/codominance-and-incomplete-dominance-key-3.pdf

Splash/Blue on the other hand is incompletely dominant, Splash + Black = A grey looking color, Dominant White + Black = White with Black Flecks, that's Co-dominance

I know this thread is old but here’s my paint pullet’s glow up! She continues to develop more spots.
