    I was on the duck color genetics chart and I put down chocolate as the color of my drake and blue as the color as my hen. I decided to switch it up and have the drake be blue and the hen be chocolate but the color results came out different. Would this be normal?

    Thanks :)

    I’m not anywhere close to a duck genetics expert, but looking at the calculator, “D” is a sex linked gene, called a Chocolate Dilution. The “Blue” gene is split on the blue bird but all it does is add to the confusion. That’s not what makes the offspring different depending on which one is the parent. That sex linked “D” gene is.

    With a sex linked gene it’s very important which parent has the dominant gene. The male gives a copy of whatever sex linked gene he has to all his offspring, but a female just gives it to her sons. If the father has the recessive version and the mother has the dominant version and you can see the difference in the down, you get sex links. Even if you can’t see it in the down, they often look different when they finally feather out. If the father has the dominant gene then all offspring will have it regardless of what the mother has. In both cases the father has to be pure for that gene (both copies at that gene pair match) or it doesn’t work. This thread talks about sex links in chickens but the principle is the same for ducks.

    No, the color results should not be the same if you change out the colors of male and female. Chocolate is a sex linked trait. If you use a chocolate drake and a blue female, you would have the possibility of producing both chocolate and lilac females. The males from this breeding would be blacks and blues.

    If you reverse the parents to a blue male and a chocolate female, the results change. Female offspring have chance of being black or blue. Males will also be black or blue.

    Hope this helps. Good luck & enjoy your ducks.
