Genetic question about spangled gene...

[Amer]

Holy heck! You're not kidding! It is going to take me a lot to wrap my head around the spangled part! I found a paper on how the mottled gene is responsible for several marking types, such as the spangled, and it's pretty thorough even if it does read like an automatic transmission repair manual! I'm going to have to read and reread, while cross referencing some terminology in order to even get a little familiar with what it sums up, but it's a good start!

Thank you! I'm going to have to play with the calculator a bit and figure out how that works as well! I was desperately looking for a chicken genetics calculator that worked much like the ball python one here : https://www.morphmarket.com/c/reptiles/pythons/ball-pythons/genetic-calculator/?select_input=t
I had taken a brief look at the one you linked, but I was positive someone somewhere had to be so in love with chickens that there would be a totally untechsavvy, simple click and play english version and never actually stopped to play with that one and kept looking since I didn't know the genotype for silver spangled! Thank you so much for providing it for me, you have no idea how much I appreciate it!

And you were right, all three do sport feathered legs! I took a look at their baby photos and Yep, they started with downy legs, the two larger ones are feathering up on their legs again, and the itty bitty is starting to show the signs of incoming growth

I had made the silly assumption that spangled worked like cuckoo or barred, only misunderstood how those genes worked as well! I've got some serious reading to do!

Now that I've got a clear understanding of the fact my understanding was incorrect, I'm even more eager to see how these babies feather out!

You've all been incredibly helpful and I can't thank you enough, it's a good thing I don't intend on breeding anytime soon, as I've clearly missed a few key points! At least you all didn't give me the dreaded news... you've got all sexlink MALES!

I hope you don't mind me crawling back for more answers I can understand as I dig through the information I did find, you've all been fantastic!

No problem! I’m always happy to help!

I should probably explain that the spangling with the mottling gene is actually spangled in Orloffs. That won’t help you unless that is the spangling you want to learn about is this type...

I haven't worked with spangled myself but I think the cross would just give you black chicks.
Why or how did you suspect it would produce sex links? Just curious.
Spangled is a gene but a result of a combination of genes.

This article mentioned that through breeding trials, spangling is sex linked to a certain extent: https://www.genetics.org/content/genetics/8/4/367.full.pdf

Thanks for sharing, that article is from 1920's and more recent research has confirmed the Autosomal nature of Spangling which is not a single gene but a combination of multiple genes that are linked to each other by a somewhat close linkage(10 to 15 map units of each other)

Oh neat! And hope I didn’t offend. I was reading about it because I have a Mille fleur roo and what appears to be a silver spangled chick. Was wondering about the genetics of it. Hence why I had both that article open and this thread

Did you get the spangled chick or it hatched from the Mille Fleur rooster? I ask because Spangling(autosomal polygenic trait) and mottling(single recessive autosomal mutation) can look very similar for example Silver Millie Fleur are mottled on a silver columbian base, that can look vary close to Silver Spangling

these are mottled based

My mille fleur rooster, as I’ve been reading, may not actually even be mille fleur because he only has white tipped feathers on his head and in his down feathers. His father was a porcelain sablepoot (the mille fleur patterning was in the porcelain) and his mother was a white silkie/OEGB mix.
My rooster does have black spots all over and a red-buff Colombian base. But the white tipped feathers are only on his head/in his down. The chick looks like this:

I’m just guessing silver spangled because I googled it and some of the chicks look like this one and I know it’s from that rooster because of other traits it has (4 toes, etc)

He may just be a carrier for mottling correct? And have spangling?

Attaching some photos of my rooster as he has aged because as a chick he had lots of white tipped feathers and as he has aged they’ve gone away everywhere except his head and down feathers. He is 6 months old now

I was thinking maybe more white would come back as he ages or after his first molt?

That roosters is mottled based not spangled based
