White Chinese female crossed with American Buff Male. Why are some of the offspring dark colored?

[jennjen2011]

I have 2 White Chinese females and I American Buff Male. This is my 2nd batch I've hatched from them and I'm just wondering why some of the offspring are dark colored when neither the mom or dad are? Attached are pics of parents and offspring.

White in geese isn’t actually their true color, it conceals what color the goose actually is which could be a number of things. White Chinese are technically brown Chinese with the dilution gene hiding the brown/grey feathers.

Geese chromosomes are ZW “female” and ZZ “male” and unlike us it’s the female who determines the sex of her goslings, certain genes, like buff, are recessive and for it to show visually in males both chromosomes would need to carry the gene whereas only one copy is required for a female to show buff visually. Without the recessive buff genes buff geese are actually grey.

So when you take a white Chinese and cross it with a buff goose, you’re highly likely to bring out what both parents carry in their genes, grey.

The blonds could end up being white or buff!

Is the dad the buff? If so he won’t be able to pass the color on to the goslings, if the buff is female she can pass it on.

Yes the dad is buff

So if you breed a white male to a buff he should throw 2 colors Diluted Males and Pied female. When you breed a solid color male to a white female. You will get pied birds. Since buff is a sex linked color he will probably throw mostly grey pied. Your lighter ones when they feather out should have a diluted color they should be boys and your darker ones girls. Once you get a diluted boy you can get back to white. In order to show white (which is actually a cover for another color) They all have to get back to Dimorphic and pied. 7 eggs hatched so far this year one white. 3 generations to get here
