Crossing a Wyandotte/Orpington roo with an Olive Eggers, what color eggs?

[AinaWGSD]

2 Genes of the same would be "homozyogous". A rooster w/ 2 blue egg genes is homozygous for blue egg genes. (My auto correct changed homozygous to heterozygous 2x, soooo... ).

An OE would be heterozygous for both blue & brown egg gene colors.

Good catch, homo=same so two copies of a gene would be homozygous.

Still trying to understand all this egg color and crosses, but, just a simple answer would suffice, if we use our SL Wyandotte/ buff Orpington rooster over our Olive Eggers (grey in color, lay variety of olive color eggs from olive to speckled brown)

Would the offspring pullet lay a form of olive? Right?

Some pictures of our crew and their eggs as of now -- and no, the roo is not old enough yet just curious thank you

The mothers DNA is what generally influences the egg colour.

Maybe, but the rooster does have some influence. Personally i think its more that the mother's DNA is more visible so it's easier to see her influence. But that's just my opinion, I don't have the genetic background or studies to support it.

It doesn't matter how blue an egg a hen lays, if you breed her with a rooster from a brown egg laying breed those chicks are not going to lay a blue egg. If you breed a white egg layer to a rooster that's homozygous for blue or brown, the resulting chicks are not laying white eggs. If you breed the darkest laying marans hen to a leghorn rooster, the resulting pullets are going to lay a lighter egg than their mother. So even if the hen's DNA has a greater influence, you can't disregard the egg color genetics the rooster carries.
