I can't calculate!

[andy4711]

I just tried to use the genetic calculator. Not even close to understanding it!
In an earlier thread, i found out that my light green-opaline-spangle cock was split for greywing, as is his skyblue mate.
They hatched 7 out of 7, and i expected some blues, and spangles. I have ended up with: 4 x l/green-full body colur greywings. 1 x l/green normal. 1 x l/green opaline. 1 x l/green spangle.
As you can see, all are some kind of light green, and only one spangle. Is the greywing gene stronger than the spangle? and why no blues? The sky blue hen was previousely mated to a sf darkgreen, and produced all colbalt young.

I'd say your cock is not split blue.

True. But i would have thought she would have passed her colour on to at least one chick, or is it because the green is dominant, she will never pass on her colour?

Yes, green is dominant over blue. All your chicks will be split for blue.

Thanks for that Rachel.
How's the weather down under?

To use the genetic calculator you need to know your mutations and how they are inherited fairly well. Once you have learnt this you probably won't need the calculator. Always remember that the percentages given are an average and you might need to breed a lot of chicks before you get a similar percentage.

The males are shown as 1.0 and the females as 0.1. The calculator assumes that the birds are light green until you select something different.

For your cock bird you need to click opaline & (sf) spangle in the visual column, and greywing in the splits column. For the hen select blue in the visual column and greywing in the splits column. Neither bird has any dark factor so leave the dark factor blank.

Here is a screen shot of the calculator showing how it should be filled in for this pair.

Nice explanation Nev

[andy4711]

Thanks Nev.
Thats a great explantion. I'm going to try it with the next pair.

Since your male bird is not split to blue When you pair him to a blue or a Green Split to blue you won't get any Blue - both Parents must carry the blue gene to get any blues. but Like already stated these babies will all be split to blue.. so When you breed them later on you can put them to a blue and get blues and green

once you get the hang of the genetic calculator it is pretty easy I've been using it for 4 years now and I love it .. Granted most of my pairs are past babies so I know what they are But i still like to go play around with it any way Plus I've had some surprises pop out of Pairs that I knew both backgrounds on - Found out You probably will never know the entire background of parent birds lol because some of these Surprises popped up way down the chain. and some popped up with birds I've bred together several times in the past Guess they just didn't feel like letting me know everything they were split to or Masking (for the Inos)
