Color genetics thread.

The splash is the hen. The rooster looks white but has yellow on him. So wanted to know how white works with other colours. Since the silkie splash crossed with what looks like a white rooster produced yellow offspring.

The pullet of silkie splash and 'white'? Rooster

When the ' white' rooster is crossed with a black hamburg hen there were 2 white and 1 black but black wasn't a solid black

I can only talk about my observations I don't have a good understanding about how genetics work but sounds like there's a lot to consider in chickens and it's not just a colour gene but other factors that affect the outcome of colours

That looks like a dominant white bird and it also has to be blue. Dominant white does not work on red pigments- so some red is being expressed in the feathers. Your male is dominant white. It is not unusual for the feathers of some white birds to show some yellow as the feathers wear.

Your white male carries only one dominant white gene. It is not unusual for a black bird to show red or white.

Thanks for the explanation. So can the red gene look yellow when mixed with dominant white? And does it mean the rooster just has one dominant white if the other pullet looks like this from same silkie splash and white rooster?

what would I get when I cross
2nd generation RSL rooster


with that leghorn hen thats beside him?

Mostly red or partridge patterned chicks. Half will inherit the dominant white, which will replace any black pigment with white.

ok thanks! I cannot imagine the comb on them chicks!

and the laying capabilities!

The male is a white-tailed red phenotype and the female is as black breasted red. If you cross the two you will get black tailed red and white tailed red offspring. The male offspring will not be completely restricted, but with red plumage similar to the male parent; some male offspring will have white tails and others will have black tails. The female offspring will have a different coloration than the leghorn hen. The females will have a plumage color similar to a red leghorn but with black stippling on the back. Some females will look similar to a red pyle but with more red in the plumage.

The chicks that hatch a redish white down color with some back markings are the white tailed reds, the chicks that hatch with a redish down color with some back markings are the black tailed reds. The down color is dependent on the E locus carried by the male, so the down color could be different.

I am assuming the male is carrying certain genes and that is what I am basing my predictions on.
