Black and Grizzle

[fastpitch dad]

What will you get if you breed . will you get a black and a grizzle.
The hen is black and cock is a very white grizzle.

What color is the grizzle? Being very white probably means that it is a homozygous grizzle, then all young would be grizzles but the color will depend on dad to a degree. If his color is black, you should get all black mottles or grizzles. Black (spread blue) tends to suppress grizzle to a point of mottling, as opposed to grizzle. Remember, white is not a color, it is the lack of color and the bird's genetic color is whatever color is present, whether you can see it or not.

So the young would from a grizzle cock and a black hen would be mottle. is that always or just some of the time .

This makes stork marked birds and he may get whiter over time. If he is a homozygous grizzle, all his babies will be grizzles. With the black hen, they would all be heterozygous grizzles and have more black than dad. Black makes them more mottled than grizzled but it's the same gene.

If he's not homozygous, they would have both grizzles and blacks.

Thanks for the help Bill

fastpitch dad, I have a pair like the one you described. A grizzle cock with a lot of white mated to a black hen. (in fact the cock looks almost like the one in your avatar). So far they have given me offsprings with three different colors.

They either produce a pure black bird, a blue bar, or a grizzle. All blacks so far have been hens, the blue bars were also all hens, while all the grizzles were cocks. Maybe just a coincidence, who knows

[MaryOfExeter]

Black is spread blue. If she was homozygous for spread, then all the babies would be black. If heterozygous, then half would be black, half blue. Because only some of the babies were grizzle, that means the dad was het. grizzle. If he was homo. grizzle, all babies would be grizzled.

As for certain birds being a certain color, I'm not sure but I think that part is a coincidence.
Or at least if I remember right.

Very good.

I didn't mention that blacks can carry blue as they are in fact blue, just spread. They could produce anything from black to t pattern blue all the way down to barless blue, depending on what they are split for.

As you say, in the Norway bird, the grizzle is heterozygous. To me, the one we've been discussing, looks homozygous grizzle but it is possible that it is het.

Also, as you say, the color and sex are purely coincidential as none of these genes are sex linked.

These pigeons could produce many other colors and modifiers if they carry them such as recessive red, dilute or a host of other factors. I have maybe tried to keep it too simple and assume that they are black and black only. They could in fact carry many other colors and genes.

The grizzle x black pair only had one good egg. The first colors are coming out . I guess in a week or so we'll know what it is going to look like.

That is intersesting, glad you followed up on the thread....baby should grow quick, can't wait to see those feathers.

Very cute baby! The down seems to be sparse which I think means something color/genetics wise .. I just don't happen to remember what that might be!
