Need Info on Ameraucana Leghorn Crosses

[ButtonHoarder]

Genetics people please correct me if I'm wrong.

If you are looking for a colored laying leghorn

I believe you may have an easier time breeding it to a legbar, as I believe legbars came from leghorns originally.

I would love to have legbars, just there are so few breeds near me, (which in the future I would like to change) and the Ameraucana is the only colored layer

 

[ButtonHoarder]

Oh yea that’s true too. It would be better for Button to breed leghorn to araucana.

I would love to have araucanas! But again, none near me

Oh man you may need to come to Mars to get some, I know your from Earth and they don’t have as many there. No I’m jk I thought your location was funny

Button, do you have an incubator? Could you by chance buy Legbar hatching eggs?

 

[ButtonHoarder]

First, this combination already exists. It's called the Whiting True Blue.

Second, the white shell gene doesn't combine with the blue to make a lighter colored blue. Each bird carries 2 shell genes for color. There are 2 types, white or blue. The blue gene is dominate so a hen only needs 1 to lay a blue egg. In a first generation cross, all offspring will have 1 white gene from the leghorn and 1 blue gene from the AM. If you cross 2 second generations the offspring will have a 25% chance of 2 whites, 25% chance of 2 blues, and 50% of 1 white and 1 blue.

The brown coating genes are separate. Neither of these breeds carry the genes for brown coating so you won't be getting any green eggs.

Oh, well even if it already exists I'd still like to breed and create my own
So it would be either all the way blue or all the way white?!
Ok, so first generation hens would most likely lay blue eggs? Sorry, I'm having a really hard time understanding any of this, is there any way to explain further? Sorry I'm a pain

No I don't yet, but I'm planning on getting one very soon. I might be able to, not sure.

Ameraucanas have two blue egg genes O/O
Leghorns lay white eggs o/o

A first gen cross all offspring would be O/o (blue egg layer) like an Easter Egger.

A second gen cross O/o x O/o would have 25% offspring with O/O(homozygous blue), 50% with O/o(heterozygous blue), and 25% with o/o (white layer).

Thank you! That helped

The thing you may have trouble with is, it's hard to tell what offspring has homozygous blue vs. heterozygous blue.

 

[ButtonHoarder]

So a second gen cross would be a 50/50 chance of a blue egg?
I'm really sorry, this is just so confusing
