Ok Im trying to figure out what the color of these two young birds would be
I really like the coloring on them a lot!

Genetically, the first is ash-red bar with traces of third bar and white flight. Homer-talk is mealy or silver or sometimes red bar. As for the second bird, it is a grizzle white flight, and it looks to be a heterozygous grizzle with possibly undergrizzle as well and of course the white flights. Homer-talk - blue grizzle w/f.

Is the grizzle gene dominant? I thought you couldn't tell if a bird was dominant homozygous unless you knew their parents?

Yes, classic grizzle is dominant. (Homozygous refers to it having two copies of itself in the bird) dominant simply means that if a bird carrying the mutation
(grizzle) is paired to Wild-type (our standard - a blue bar), that the mutation (in this case grizzle) will appear in the offspring. If you have a homozygous grizzle (carries two genes for grizzle) mated to a wild-type bird, then 100
% of the young will be grizzle. If you have a heterozgyous grizzle (carries one gene for grizzle only) then 50% of the young of both sexes will be grizzle and 50% will be wild-type (non-grizzle).

You can sometimes tell if a classic grizzle bird is homozygous because it often tends to go almost white across the wingshield and body with pigment mainly showing up in the wing tips and tail tips only. Heterozygous grizzles are the "classic" dragoon grizzle color (blue bars with grizzling.)

How could you tell a dominant is homozygous just by what if looks like. Couldn't it be heterozygous dominant?

I guess my question is how can you tell if somthing is homozygous just by looking at it, unless of course the gene is recessesive?

Sorry don't know to much about pigeon genetics.

well I always called them silver bars before then someone told me I was wrong and called them red mealy bars , but still if you asked me outside of the chat I would say it was a silver bar lol :p

Because in grizzle, homozygous birds are much more white, and often turn completely white (in ash-reds) or stork (in blue). Heterozygous grizzles are mostly colored, with that salt and pepper effect on the feathers.
Typically the appearance of a color/modifier is much more strong when homozygous, and some are pretty easy to tell just by looking if it has two genes or one for that trait.

Ditto here! My mentor was a no nonsense kind of person.Filling out the race sheet would have been twice the size, had we recognized all the variations.
The first one looks like "silver" and the second a "grizzle"...the band numbers tell me if it reigned or failed.

Being both a genetic nut and a racer, I have to adjust to all the names. On race sheets I still use the typical 'homer colors' just because you can only abbreviate but so much! :p
If its red bar or check, that's what I put down. Even if it has indigo or whatever. Velvets become 'dark checks' and red velvets I just put down as 'red'. Blue indigos become 'chocolate'. I still refuse to put down silver for any of my red bars though. I'll only call it a silver if it turns out to be a lavender, or barless red. Guess that's just my pet peeve :rolleyes:
