Ok I went back to the first page and reread how paint silkies started. I am pretty slow person when it comes to learning through reading. I do better experiencing. So I still have to ask if paints are from black hens to white rooster where does the other colors come from in them ?
Whites can and do hide just about everything. Even blacks hide genes.
Remember, all chickens have 38 chromosome pairs, each with many genes. Whatever mix of genes an animal has contribute to its appearance. In most cases, the presence of a single gene (or even a matched pair) does not turn OFF all the other genes present in a bird, and even the ones that effectively turn off other genes do not prevent them from being passed to offspring.
