Goose Genetics - Recessive Buff

[NapoleanGoose]

Hi,

Imagine my surprise when I got buff goslings out of my flock of grey Toulouse! I traced it back to my 5 first geese ( the new gander is from a diff. breeder) and remembered that the breeder had Buffs and Greys and had said he was puzzled only to get grey goslings when he raised my birds. I am thinking that I have recessive (split?) buff birds then.

So I used a goose color calculator, but it would only let me set the gander as a buff carrier. If I have a split buff gander then I should get 50% grey ganders 25% grey geese and 25% buff geese. I am wondering though, if both the male and female carried the recessive gene, would there be a higher percentage of Buff? I'm calling people who've I've sent eggs to to check and see what they are getting, but most wont have hatches for another week at least. I am thinking this especially because of my own hatch. Out of 16 eggs 6 made it to hatch day ( there was a heat spike ); ) and out of the 3 that hatched, 2 were buff. I mean. Unless I was just VERY VERY lucky that seems like very high odds.

And while I try and get a grasp on this, If I'm right, if you breed a Split buff gander with a buff female you'll get 25% male and 25% female buffs, 25% split buff and 25% grey right? And since again, the calculator will not let me use a split goose, I did it by paper. If I have a split buff goose to a buff gander, I should get 25% split ganders 25% split geese and 25% buff gooses and 25% buff ganders.


Any idea which is best to get a little bit of buff with the least work? I would love to have a buff breeder out with my other geese, but I don't whether to keep a girl or a boy. Thanks a bunch guys, genetics confuse me so much but they are so necessary.

Buff in geese is sexlinked. Therefor a female can not be split. Therefor also it's best to keep a male buff breeder.
If the buff were not sexlinked it still would not be worse than a female buff breeder...

And you can add genes yourself to the goose calculator.
Go to the bottom green bar type for "symbol" Bu and for "effect" Buff. Press button "Quick add Gene". Done.

Thanks Henk! Is there any way to get a male buff from the stock I have now or will I only have splits and buff girls?

If your geese stick to the sexlinked theory then no.
But goose genetics is a shaky terrain.

Henk is correct if you are thinking of just this year. If you know who is responsible for the appearance of these buff goslings (all female) you can breed some of these young buff females back to gray ganders split for buff. You know they are split if they produced a buff female. THEN you will get buffs in both sexes as well as more split ganders. Some of this years gander goslings will be split to buff but you have no way of knowing which ones without test breedings. Buff is not a simple recessive. It is sex linked which is why a goose is whatever she looks like and split to nothing. A gander who is gray can be a buff carrier and you have that now.

Thanks. Good thing I know who's responsible. If he already has two mates will he not accept one more or do I need to take one away? Or is that worse?
