Call Duck Genetics

[Borncountry419]

Yeah I did. And the images did work. Thanks a lot!

I'll need to sit down and read it when I have a chance.

Unfortunately I accidently "broke" link to pics/diagrams on a couple of occasions

, so have now uploaded them to this site. They aren't quite as large as would like, nor therefore clear; one reason I never uploaded here initially img/smilies/smile.png" alt="smile" />">https://www.backyardchickens.com/forum/viewtopic.php?id=410593

I know this is an old topic, but I came across it while trying to get a hang of all this genetics stuff and thought it would be easier to continue this one rather than start a new topic. I'm not new with genetics in general, but I'm a total novice with duck genetics (only started reading about them tonight) so bear with me..

I already read the basic mallard genetics topic (linked on this one) as well, but I'm still not unerstanding something... Maybe the time (2 am here), foreign language and the fact I've previously studied cockatiel genetics and seem to think duck genetics trough them have something to do with it... However http://www.edelras.nl/Henk69/kruisingEend.html calculator has got me all confused. According to it if I put a black drake together with a normal mallard duck it says they will have black self bibbed babies. Where does the bib come from? How would I get black babies (other than black+black)? I'd understand if the homozygous black (E/E) would mask the bib where heterozygous black (E/e) wouldn't, but it doesn't seem to be the case since the calculator also has bibbed E/E birds. Is there a mistake or am I totally missing something here?

And another thing I was wondering was if I could ever produce black ducks from black bibbed ones? Wouldn't have to be the first generation, but in the long run... are the genes separateable? (Is that even a word?) By my logic it should be possible because why would two dominant genes need eachother in any way, but again I could be totally wrong? (...again I'm applying cockatiel genetics to ducks.)

I could possibly be getting call ducks spring 2014, so I'm not in a hurry to get this, but I just have to understand this before that.

I will appreciate anyone trying to explain this to me as the information really seems hard to find...

EDIT: I think I found it! It's the dusky isn't it? Completely black is visual dusky (md/md), but shows the bib if it is only split to dusky or doesn't carry the gene? If so, I could pair a black bibbed call with a dusky and their offspring with another dusky to produce a few completely black ones?
