Mouse Family Tree

Post by kawmice on Sun Apr 08, 2012 4:12 am

Ok guys....... just bare with me here. I have alot of questions and am in need of some confirmations on these genetic makeups.

Ok..... this is what Myself and a few others have determined....

Breeding Pair:

Pumpkin: Avy/* A/a^t e/e Sa/sa C/C
Nike: a/a E/e Sa/sa c^?/c^? Spl/Spl

**What does E/e mean? Does this mean non RY?
** Could c^? actuall mean c^ce?? 2nd gen gave me a BEW and a Beige (see below)

First Gen pups at KAW Born 1/28 - I need confirmation on their coding. I am not sure I got them right.

Agouti Satin Buck: Avy/* A/a^t sa/sa c^?/c^?
Black Tan Buck: a/a^t Sa/sa c^?/c^?
RY Satin Buck: Avy/* A/a^t e/e sa/sa c^?/c^?
RY Buck: Avy/* A/a^t e/e Sa/sa c^?/c^?
RY Doe (4 total): Avy/* A/a^t e/e Sa/sa c^?/c^?

now...... my second Generation was unexpected. One of my bucks matured at 4 weeks and got one of the girls pregnant. I believe the sire in the RY Satin Buck and the mother is one of the RY Does (satin carrier). I was a bit confused by what I got, but this are starting to come tigether. I need to know these guys possible genetic code and I then have other questions.

The pied carriers all have white tip tails and feet.

Agouti Satin Pied Carrier Doe: Avy/* A/a^t sa/sa c^?/c^? s/s
BEW Satin Buck: ce/c sa/sa (what else?)
RY Broken Buck (no sootyness at all): e/e Sa/sa s/s
RY Satin Doe: Avy/* A/a^t e/e sa/sa c^?/c^?
Beige (poss satin) Buck: ce/ce sa/sa
Black Pied Carrier Satin Doe: CULLED
Black Pied Carrier Buck: CULLED

Now..... I would like to know all of their genetic codes. I know I have some of these guys wrong. I am trying though! lol

Also....... would the s/s come from Nike since he was a splashed?
The BEW - is he considered a high white since his siblings are s/s? Would he be Ivory or BEW?

I know lots of questions.... I would probably have more but the chair I am sitting in at work is very uncomfortable and distracting! lol

E/e = not RY

c^? I've never seen before, but it's a good way of saying the mouse has an unidentified c-dilute that is not C or c.

Agouti satin buck = A/* C/c^? E/e sa/sa Spl/* (remove the a^t unless this buck is tan)

Black tan buck = a^t/a C/c^? E/e Sa/sa Spl/*

RY satin buck = a/a C/c^? e/e sa/sa Spl/*

RY buck = a/a C/c^? e/e Sa/sa Spl/*

RY does = a/a -- you've listed these as A^vy and a^t also, are they tan brindles? Besides, you're allowed only two genes on the A locus. If they are tan brindles, they'd be A^vy/a^t -- C/c^? e/e Sa/sa Spl/*

I am wondering if Nike's breeder told you she is Spl/Spl, because she could be splashed and be Spl/spl. Splashed shows only on mice without C or c/c. That means splashed shows on any combination of c, c^h, c^e, or c^ch. Some of your mice technically work out to C/c^? Spl/Spl, which is called "hiding splashed". It can't be called "carrying splashed" because Spl is dominant, but it seems to work the same way, because a mouse who doesn't look splashed can have splashed babies, if mated with another c-diluted mouse. So...if Nike is Spl/spl, then some of her babies are hiding splashed, and some are not, and there is no way to tell which does and which does not except by breeding.

I will leave your second generation genotypes to the next poster.

You are doing really well with your genetics! Keep at it! The more you discuss them with people, the better you understand it. Worked for me!

BTW, you don't list any brindles per se, but you keep including A^vy on the A locus. A^vy is brindle. Of course, brindle stripes often don't show up until a mouse is three months old, so you may need to revise some of your genotypes. I've noticed you've marked all your RY mice A^vy. They could be both, or they might be E/e and undermarked A^vy (not visible stripes), or they might be just e/e. Sometimes you can tell as they get older (like if they grow stripes). Sometimes you can't tell at all, except by breeding.

Stina and I were a bit confused on my mice and some people thought my agouti look brindle to a point so Stina suggested that mom may have been Avy and e/e.

I have the pictures posted in mouse litters. Could you go to my post there and take a look? I would really like your input. It will answer a lot of your questions as well. And thanks soooo much for helping!!!! It is hard since genetics was never my strong point. I am trying my best though! Happy I really want to learn all I can. Happy

Post called "Pumpkin's Litter"? I see three posts and no pix there. Would like to help you by looking at the pix. I am very tired. Tell me more specifically where they are, please. Will look tomorrow when I'm not tired!

I forgot about that post! lol

http://www.themouseconnection.org/t373-my-weird-litter - this is the one I meant. The newest litter definately has a RY broken in it. To me the mice just look to be sooty RY, not undermarked brindle.

and could c^? actually be c^e since I did geta BEW and a Beige from my newest litter?

And thanks alot for helping!!

Littlesniffs - there will be a quiz tomarrow so make sure you study hard! lol

Well- checked on the pups today and also culled the agouti pied carrier. I noticed that my BEW satin looked a little off white. He is actually a beige satin! So I am pretty sure the c^? Is indeed c^e

Sound right to you guys?

Well- my second gen litter is growing fast and today I had a little unexpected suprise. My e/e doe is indeed A^vy! Noooooo!! At least I found my missing genetic piece/code. They are undermarked brindle and not ry. And my agouti boy (now 2.5 months old) is looking more and more like a sausage of an overmarked brindle. Obviously has the obesity gene as well.

Sad I was going to usr tje ry for many other lines including my ry satin angora line. Grrrrrr .....

Well I am now offering my newest pup for adoption. I am already keeping one of the older does and my big boy so I do not need her. Lol

Her brother is clearly a ry broken though. I am confused any insight would be apreciated.
