Bl/B/S Ameraucana color questions . . . advice please

so then why does the chicken calculator differentiate between the rooster and the hen? does it ever make a difference? well I guess it does with sex links right?

Katy,
I am not so convinced that "over" does not mean what you and I think.
In genetics there is a rule to put the roo first so black * white means black rooster * white hen.
Using "over" would clarify that rule i.m.o.
black * white = black over white = black roo with white hen.

Same story with "self blue". This evolved from solid blue to lavender, which is not the same.

Here

Black x Black = 100% Black

Black x Blue = 50% Black, 50% Blue

Blue x Blue = 50% Blue, 25% Black and 25% Splash

Splash x Black = 100% Blue

Splash x Blue = 50% Splash and 50% Blue

Splash x Splash = 100% Splash

You can't breed blue to blue and get 100% blue. You can breed a Black roo to splash hens or Splash roo to black hens which is what i'm doing snce itsso much easier to get Jersey Black Giant hens than Splash Hens.

sorry Katy i told you wrong on the bluexblue and the over thing you can switch the color names around if you like to fit your circumstances......so sorry!!!

ya sex-linking it does but any other time i doubt it but id try to stay realistic so if you no your going to use a blue roo then use a blue roo on the calculator it will give you more accurate results.....and the same with the hen but the bbs thing it shouldnt matter but dont take my word totally to heart ive been wrong before

greencastle - no problem!!!! I saw that and realized it was an error so no big deal.

Henk & sonoran; so the way I am seeing it is that sometimes you can or can't see the difference roo color over hen color vs hen color over roo color . . . but probably there is always a difference in the gene pairs whether you can see it or not . . . and that this could make a difference down the line . . .

Whew, I soo want to get into this but my brain is just not up to it!

Most often it is the sex linked genes which make the difference.

BTW, lots of people have a bit of trouble getting to grips with poultry plumage genetics at first.

And even way down the line....still makes me crazy trying to figure out genetics.....and other trying to teach it to me.

Because it does sometimes make a difference, there is a convention for how one lists a breeding pair. It provides better communication. Just as there are conventions on capitalization, spelling and punctuation.
