Egg color question

[HonkABC]

Would a green laying hen crossed to a rooster with two brown laying genes, would the offspring be 50% green egg and 50% brown egg? Thank you.

You should get olive eggers.

So all the offspring would lay green eggs?

I think so. brown + blue = green, and the brown is a bloom that is laid over a Blue egg. so they would get a copy of blue, which is dominant to white, and would then "paint" the egg so to speak, as brown and blue are different parts of the egg, and green eggs are often blue on the side of the shell facing the yolk, and only green outside.

I thought that half the offspring would receive a blue gene and a brown gene, while the other half would get two brown genes, because one parent has one brown and one blue, and the other has two brown. Would all the offspring get a copy of the blue gene?

No. Half will get blue and half will get brown from the green egg parent

Your green laying hen has at least one copy of the blue gene, possibly two copies. There is a not specific brown egg gene but if your rooster is of a brown laying breed we can assume he has zero copies of the blue gene.

If your hen happens to have 2 copies of the green gene she will pass on one copy to all of her offspring and 100% of her daughters will lay some shade of blue/green eggs

If you’re hen has only one copy of the blue gene she will pass on the blue gene to 50% of her offspring and the daughters who inherit the gene will lay some shade of blue/green. The daughters who don’t will lay some shade of brown.

So egg color genes are made up of more than two other genes?

 

[Tstraub]

There are two colors or egg shells white and blue. This is controlled by the blue egg gene. If a hen has one or two copies she will lay blue. If she has zero copies she will lay white

Brown is a pigment that is laid on top of the egg shell. Brown on top of white makes tan or brown. Brown on top of blue makes green. The bloom goes on top of the brown layer and can further tint the final color and change how shiny or dull it appears. There are somewhere between 8 and 13 different genes that can affect the brown pigment and bloom

Generally speaking if both parents lay dark eggs the offspring will also lay dark. If both lay light the offspring will lay light colored eggs. If one parent lays light and the other lays dark the offspring will likely end up somewhere in the middle.

Thank you!
