Color genetics thread.

A "white" question: Does a single dose of recessive white in a colored hen express itself with white flecks around the head? I have a black shamo hen like this, and also a bronze thai.
Another: Will a double dose of rec. white (in a rooster) still allow 1 or 2 lightly colored feathers? He is out of a creole shamo cock and above mentioned black shamo hen.
 
white with leakage....  one copy of dominant white.  This look is very typical of a dominant white crossed with other color chickens.  very cute...

I did some reading online about dominant white crosses, and agree. Thanks for giving me a starting point to research.
 
also i have this a New Hampshire Red Rooster,

who i want to breed with this, an unknown breed of hen unless anyone can tell me what she is at a glance.

next spring i want to breed them. anyone know what i'll get?
The offspring will be similar to the rooster. She is carrying genes that are also found in the rooster. The rooster is carrying dominant genes that will cause the offspring to be similar to him.

The black in the roosters breast- I can not remember what is causing the expression of black; I know there is a genetic reason, but it will not come into my head. I have notes on the subject and will have to find them. Most black tailed reds carry the columbian gene which usually clears the black from the breast. Checked my notes- sometimes the columbian allele does not take all the black out of the males breast.

It may be some combination of the mahogany gene and the columbian gene.
does that mean i could end up with white in my chicks? i know columbians are white with black neck streaks.
