Since the silver duckwing rooster is SS (silver) he’ll always pass on an silver gene, and it’ll go to every offspring male or female. The hens, since they are gold (wildtype), are s+ which is located on the Z chromosome. Roosters are ZZ, hens are ZW, so the pattern can only be passed onto the boy offspring from the hen.

So the F1 males are S/s+ which are goldens. The F1 females will only be S, and so they will be silver only.

Did that make sense?

For me it did.
I wish I could explain it like that.

Yes she explained it great for a noob like me.

Kinda.

I went back, re-read it, and it was super all over the place so I figured it wasn’t super clear.

Oh gosh, thanks ya’ll, but I really thought I was not clear in that post.

You did good. So good you almost went over my head.
I'm just a hillbilly so might have to dumb it down for me to keep up.
I'm kinda new at genetics.
Want to explain the barring with this cross?

I wouldn't have called her over so quick if I knew she was this smart.



I kid Lil K.

Aw! Thanks. I’ll try to keep it simple.

In general, in sex-linked crosses, the hens determine the patterning of the male. Z and W are the sex chromosomes, with Z being the most important and holding genes while the W doesn’t do much but tell the body to produce female hormones/organs.
ZZ - male
ZW - female

The barring would work the same as the gold pattern, since the females only have it and it’s also on the Z chromosome. So just as the gold can only go to the males, the barring will also only go to the males. So all F1 male offspring will be sexable at hatch since they’ll have a white spot on their heads.

Female F1s won’t have any barring at all.

I mean, I can hush if you’d like.

So we have the wild type (duckwing) figured out.
We have the sex link silver/gold figured out.
Working on the barring.
So that leaves the mottled gene for Kiki to figure out for us.

No!
