what will I get from a white call hen and a blue fawn call drake

[cat1994]

Hi all, I bought a pair of blue fawn call ducks so I decided to sale my white calls, but I really like one hen so I kept her. I was wondering if anyone knows what the cross ducklings will be, from my white call hen and my blue fawn call drake? thanks for any help

We have some color gene people on here, one of them is bound to chime in on this.

A lot of it depends on if the White is masking anything-if so, you could have a rainbow of babies next spring.

Masking? Sorry I don't really understand?

it is a pure white call hen from pure parents

is that you mean?

White, when you have a double dose of it, is a gene that masks (hides) any and all other color genes your duck carries. Your duck could carry any combination of color genes underneath, and you'd have no idea untill you crossed her with another duck that is not white. There is no way to predict the outcome.

Your ducklings will carry one recessive white gene, and show a combination of both parents' color genes. If you later cross these ducklings together again, you'd get 25% whites again.

The white is masking "everything", & what is being masked could be "anything". You do have a good idea what the Blue Fawn drake is bringing to the mix because you can see it (maybe not everything though). Colour/patterns produced in progeny bred will be influenced by interactions between the two (genes from both parent birds) & combinations can vary considerably, depending on what is passed on, or inherited.

Makes for great expectations come hatching time

Masking means hiding, ie, all genes for colour/pattern (whatever they may be) are still in the white bird but we can't see them; two doses of the recessive gene for white either prevents melanin (eumelanin & pheomelanin) production or, prevents melanins produced from getting into the feather.

To get some idea, & a great way to learn is to try different gene combinations on the calculator Here. Try turning one of the birds white by selecting c/c in drop down box. Then change other combinations on same bird & you will see that the bird remains white regardless of colour/pattern genes @ other loci. Then try calculating outcomes between the duck & drake while varying gene combinations! I have started you off with a white drake & wild-type mallard duck.

Cheers

Thanks so much I understand now I’m excited to see what comes from the cross
