BYC Genetic/Breed Calculator Huge Task Ahead!

This is strange...in order for a Plymouth Rock to meet the standard it must have yellow feet. However, the Partridge rock is red based which would give it a bayish colored leg. The only way a Partridge Rock could have yellow legs is by it containing a Di/Di Dilute gene which would render the red base buff...puzzling a wee bit...

Welsummers are red based and they have yellow legs.

Hey, quick question guys...do genetically Columbian birds contain a hidden partridge e^b/e^b?

They can be partridge, wild type or wheaten.

Odd.....

Here is something even more puzzling...Blue Plymouth Rocks must contain yellow legs, yet only splash can sport that apparently?

Be sure to research the places/websites you are using to research now.


Remember not everything you read on the internet is true/fact.

People don't even know the standard genes of egg color anyways. Brown is an open color. Let's focus on brown's relation to other egg colors, like blue, green, and white.

it looks to me like there are 3 layers to egg colors. base color, outer shell color and then the bloom has it's own color.

white eggs are an absence of color in all 3 layers. Brown seems to only be added at the second and third layers, BUT I would guess that Marans eggs are so dark because the brown is added on the first layer. Blue is added at the first second and third layer.

green is when blue is combined with brown.

Brown and white are co-dominant. :/ which means that a cross with a white layer and a brown layer will make for a lighter brown color egg. but with gender dominance....

if you cross a white layer roo over a brown layer hen the resulting shell color of the offspring will be darker, than
a brown layer roo, over a white layer hen.

Assuming genetically the two parent birds for each the white shell, and brown shell were identical and the only difference was the gender.

Make sense?

I'll have to do more research but that's what I've come up with so far. The Marans coloration was just my own guesswork, I'll have to actually look that up.

Blue Wyandottes can too. https://www.bing.com/images/search?...07992321470825818&selectedIndex=24&ajaxhist=0

isn't that due to the splash being crossed with black to get blue?

Yup...LOL. I am basing my discoveries on actual chicken genetics...but I found the answer...

(Id/-) Inhibitor Dermal Melanin is the gene which allows Blue and Black birds to be Yellow Lightshanked
