e/e and A^y

I've just bred an A/a E/e x-brindle to an A^y/a e/e. I've saved four babies. Two are light yellow-orangey and two are dark yellow-orangey. I'm assuming the dark ones are agouti. But how can I tell which are A^y, which are e/e, and if any are both? (I know. Pix would be useful. Working on it!) (Stina, these babies are from CSB Dreamweaver x CSB Golden Monkey.)

Here are pix:

Golden Monkey is Ay/* E/e, not e/e.

At any rate.....I don't think you would be able to tell e/e from Ay/* or Ay/* e/e........

Cute bubs though!

Yo! OK. That's happens when I do genetics by memory. GM is A^y/* E/e and Dreamweaver is A/a b/b e/e (right?). (My computer died and I'm up in the living room, camping out on a spare. All my mouse stuff is down in the basement.) So, the answer to my question is, there's no way to tell. Shoot! Some people asked me for A^y babies from this litter. So what do I do? Give them babies and tell them to breed them to something not */e or A^y/* and if they get red babies, they've got A^y? Oh, so would the e/e (or A^y) agoutis be so-called "golden agoutis"? (And what I wanted was an e/e or A^y x-brindle, but did I get one? Noooooooo! I get to wait three months and try again!)

I agree, I don't think you'll be able to tell the difference. The only way would be to breed them.

On top of that, some could be Ay/- e/e which would make it hard to tell even if you bred them!

Yeesh! Thanks! I never thought of all this when I bred them. I was hoping to get a red x-brindle! A^y/* or e/e didn't matter to me originally.

This is why I haven't kept any Ay offspring when I've bred an Ay mouse to an e/e mouse...lol

Dreamweaver is a cinnamon brindle, NOT e/e...she carries e. She'd be A/* b/b E/e Mobr/mobr

So waitaminnit. Nobody's e/e. That's right. They're both E/e, then? It is very late and my mouse book is downstairs....

So THIS is why A^y is rather rare (according to TFM)!

Very cute pups!!!

Umm...... what is the difference between an E/e mouse and an e/e mouse?? I am a bit confused here. lol

e/e is recessive yellow, 2 copies of e, the recessive gene. Writing E/e just means that there is only one copy of e. The big E represents there being no recessive gene there.

So would E/e just be a yellow mouse? Or a dom yellow gene that is not Ay?

E/e would just mean that the mouse is not yellow, but carries recessive yellow, or has one copy of recessive yellow.

If the mouse was (a/a (black) E/e) then the mouse would be a black mouse that carried recessive yellow.

Ah! Ok. Thanks for explaining that to me. Lol
