BYC Genetic/Breed Calculator Huge Task Ahead!

[Rose Quartz]

I think I'm done with looking into egg genetics. here's a link to my spread sheet:
https://docs.google.com/spreadsheets/d/1OOjHH5UaHbd4qoRNPF0jvDu4g26H42NZWdK403pCX8w/edit?usp=sharing

feel free to copy and paste it. so you've got a copy.

let me know if it's not exactly what you're looking for, I do have other stuff that could be added, like the blue Oo, I just didn't want it to look like the zinc chelate was only in Oo, it's a secondary chemical to Biliverdin, that's all.

I could do something like different gene expressions if that's more what you're looking for, showing the different outcomes from crossing egg colors. maybe incorporating the egg shell color pictures to the spreadsheet if that's possible.

No kidding. It's not a good time right now with our animals.
I am praying we won't have to liquidate our flock

Same. Ours are all sick.

It just stuns me...aren't we all in the same world?

Exactly

I appreciate your efforts on this matter, I would like to point out a few things, I would appreciate if you type the genetic nomenclature in the right way: Dominant genes will take precedence over recessive, dominant genes first letter will start with capital letter, recessive genes in lower case, the + sign means the gene is of a wild type background and currently found on Red Jungle Fowl so not a mutation of what is currently found in wild RJF. Commas and spacing, please use them to separate the allelic pair from the rest of the genetic make up, for example a red jungle fowl with slate shanks is described as. e+e+, W+/W+ id+/id+(male)

Clear White Shanks
W+/W+, Id/Id(Id/- for females) based on any e allele(E, ER, e+, eb, eWh, ey) W+/w will also display clear white shanks.

Clear Yellow Shanks
w/w, Id/Id(Id/- for females) based on any e allele(E, ER, e+, eb, eWh, ey)


Slate Shanks of any shades(as to reduce any other plumage diluting factor that will enhance or dilute it's effect but not negate it entirely)
W+/W+, id+/id+(id+/- for females) based on any e allele(E, ER, e+, eb, eWh, ey) W+/w will also display slate shanks.

Willow Shanks of any shades(as to reduce any other plumage diluting factor that will enhance or dilute it's effect but not negate it entirely)
w/w, id+/id+(id+/- for females) based on any e allele(E, ER, e+, eb, eWh, ey)

The only reason Barring has any effect on shank color is because it's linked to the Id(dominant sex linked dermal inhibitor) by like about 11 map units(Centimorgan) on the long arm of chromosome Z, that means that about 90% chance of a barred bird carrying Id therefor clear shanks, but with large enough breeding one can produce B, id+ recombinants


Not only blue, but dominant white will dilute the shank colors, but not so much as to negate the effect..


So I suggest to keep any Inhibitor or enhancer away from the calculator and obviate the e allele from it, just to keep it simple, W+/W+ id+/id+ will produce slate shanks(the shade is of no concern), w/w id+/id+ will producer willow shanks(the shade is of no concern).. quite simple if you ask me.

Thank you! And thank goodness I don't have mixed up genes and have to make the y real small on ey. I knew what and where dominant and recessive genes went, and what the plus meant, but that was it.

I can't find the abbreviation for brown egg shell color. I did however find this:

https://www.ncbi.nlm.nih.gov/pubmed/26240390

the brown pigment is applied through the whole shell.

But what about mine? Are mine strange? Or does the pigmentation vary per chicken on whether it is mostly on the surface?

You will not find any, as the brow egg shell color is a Polygenic trait that expands multiple genes, at least two of them are sex linked

Sexlinkage in eggs. Sad. How are you supposed to find sexlinkage if half of the offspring are male?

Just a quick question @Feather Hearts , @Cyprus ,and @AMERAUCANAS4REAL , should we crop the birds out of the pictures for ease of viewing in the calculator?

Yeah.

@AMERAUCANAS4REAL you have the SOP, can you look up what color redcap earlobes are supposed to be? our list says white, the website I'm looking at says red, BYC doesn't say in the review, but all the pictures have a mostly red lobe with some white, which would not be to SOP.

Red.

Red.

What do you mean are yours weird? white shell on the inside is normal, and so in tan shell. I don't know which gene controls it, mind you, but the brown is or can be deposited through the whole shell. it is concentrated on the outer most layer though. (I asked Fanci, her Marans eggs are white on the inside.)

Wouldn't the green eggs be O/O,P/P right? When you put them together and all?
So white would be o+/o+,p+/p+
Blue would be O/O,p+/p+
Brown would be o+/o+,P/P
is that right?

Hmm. Maybe some are more creamy on the outside because they are more evenly dispersed. I guess certain genes must control it, because my eggs were always that way. Also, we are getting our first white eggs from our Anconas, so now I get to compare.
I agree with the earlobes not being linked to egg color. White egg layers must have them because that is the more "wildtype" earlobe as well as egg color and they just happened to get the luck of the draw that way. I also read a whole scientific article on it, and got no genes out of it. I was thinking, why write an article if you don't actually have answers?
I also think your egg research is a qualified success. And my leg color stuff, but I got a lot of help with it. Who knew there were so many patterns affecting it?

Still not getting alerts...
there's quite a bit to read through. What's going on?

uh.... except the brown is co-dominant, more like, Pp/Pp if that makes any sense...

the way I intended to write it would be:

o+/o+ = white
o+/o+, Pp1 = light brown
o+/o+, Pp2 = slightly darker brown
o+/o+, Pp7 = medium brown
o+/o+, Pp13 = marans dark brown

O/O = Blue
O/O, Pp1 = light blue-green
O/O, Pp2 = slightly darker blue-green
O/O, Pp7 = medium blue-green
O/O, Pp13 = Olive egger

O/o+ = blue, or lighter blue
O/o+, Pp1 = light green
O/o+, Pp2 = slightly darker green
O/o+, Pp7 = medium green
O/o+, Pp13 = Olive egger

the brown color works differently from the blue and white it works with them instead of completely canceling them out.
I know that each gene isn't contributing the exact same amount of pigment, but breeding can result in lighter or darker eggs based on what the parent stock has. So my brown numbers are more just a way to say how much brown pigment has been expressed.

I;m working on an update for the entire thread ATM. I'm about halfway done re-reading everything.

on my color chart the one that I have called oo tinted with no number is the brown that goes through the shell all the way. I don't have that one included in the green charts because the blue shell would fill the space where that would normally go. any egg that's white on the inside would only be using 12 of the 13 shades I have. it doesn't make much difference in the final shade for brown over white.

So the cool thing I learned about leg color today.
Ok, so possible fathers of this Easter Egger pullet I hatched a while ago...
Buckeye wheaten based yellow legs
Welsummer duckwing based yellow legs
Mother
Ameraucana wheaten based slate shanks
So how in the world did I get white legs out of two colors that aren't white? Genetics.
If the sire was
w/w, Id/Id, e+/e+
or w/w, Id, Id, ewh/ewh
And the dam was
W+/W+, id+,id+, ewh/ewh
Then the offspring would be
W+/w,Id/id+, ewh/ewh or
W+/w, Id/id+, e+/ewh
White legs because white is dominant! I think I finally get it. I hope the dad is a Welsummer, so I can get olive eggs.
