Default Genetics?

Hello,

So I am doing some reading about the different mutations and it got me wondering what Max and Stars chicks would look like in the hypothetical situation they were to breed. That said I do NOT intend to breed them. I am just curious how the color mutations would interact.

I am also kind of confused about how males (like Max) can be opaline? I get its passed along by the X chromosome and I know the basics of genetics but something about the opaline mutation is really confusing me.

I'm doing some reading about the gray wing mutation and the dark factor...
>.< Lets just say I'm learning more about the color mutations and I am super confused.


For reference here are the two in question...

Star (I maybe off with her mutation but the light green opaline graywing is my best guess...)


Max (sky blue opaline)


Again this is just me being curious.

The images are not working...I am going to investigate and try to fix...

Hey there

I can't see the photos you posted (Photobucket does not let you post photos on forums anymore), but while you work on getting them up (try imgur!), here's an article I wrote about mutations. There's a specific section on sex-linked genes that explains how they are passed on to males and females; I believe the example used is the Ino gene but for all sex-linked genes, the inheritance patterns are the same

I did read the link...I think I'm getting stuck on the XY thing...with opaline being only on the x chromosome... Somewhere along that line I am getting lost...




Victory is mine!
Mr. Max


And here is my little lady Star.

I can see Max! He's beautiful, and yes, sky blue opaline.

Let's see if I can explain it better:

Opaline is expressed on the X chromosome, as you know. Females are XY, males are XX. The gene only is shown visually when it is carried on all present X chromosomes. For females, they only have one X chromosome, so when they carry a sex-linked gene (like opaline), it is expressed visually. Since males have two X chromosomes, they will need two copies of the opaline gene to express it visually.

This means that males can carry opaline (be split for it) and not show it visually; when there is only one copy of the gene (on only one X chromosome), they do not show it visually but can still pass the gene on to offspring. If a male is split to opaline (meaning one of two X chromosomes has the opaline gene), there is a 50% chance that he will pass the gene on to his chicks. Only daughters will show it visually if he does, because females get their X chromosome from dad-- they have to get the Y from Mum because females have the Y chromosome. None of his sons will show opaline visually, but half of them will be split to opaline (again-- two X chromosomes mean that the one copy from Dad is not going to show up). For a male to be opaline, like your Max, his mum must have been opaline-- each parent gives one sex chromosome (either X or y) to each chick, so the one given to him by his dad would have to have opaline and the X from his mum also had to be carrying opaline. If the mother's sole X chromosome was carrying opaline, she showed it visually.

I hope that helps somewhat-- that's probably just more confusing, but I tried

Nope that makes sense! I was getting who had what sets (XX and XY)

So then with Max and Star any hypothetical offsring would be at least Opaline, how would the light green graywing interact with sky blue?
My guess would be the chicks would be green opaline, but not graywing, assuming Max isn't split for it (maybe? I'm new to this) This is all going off the guess that Star is also opaline.

Yep, I agree with your assessment for Star's mutation!

All chicks would be opaline, all would be green (unless Star is split to blue), and all would be split for greywing (none of the chicks would show it visually as it's a recessive mutation unless Max was split to greywing).

That is so cool! The way the color mutations work is fascinating. Thank you for the information!

Like I said, I don't intend to breed them. Its still interesting to see how the different mutations work.

One last question how does the 'dark factor' work? Like with Star being a light green?
Thank you SO much for all the info!

Dark factors are a bit confusing, but they work a bit like this:

A bird can have a total number of two factors maximum and zero factors minimum-- 0 and 0, which is sky blue/light green, 0 and 1, which is cobalt blue/dark green, and 1 and 1, which is mauve/olive green.

They are passed on just like incompletely dominant mutations. If you have a parent that is cobalt (0 and 1) and a parent that is sky blue (0 and 0), then the chicks could be 0 and 1 or 0 and 0. Does that make sense?

Yeah that makes sense. So in this hypothetical situation With Max being sky blue and Star being light green both are 0 and 0, so their hypothetical chicks would most likely be light green. This is going off of the assumption that star isn't split to blue.

I'm starting to get how these different color mutations work I think...

Yep, they're both 00 and 00 so assuming that she's not split to blue, all the chicks will be light green

Glad you're getting the hang of it
