FINALLY got a fat mouse!

[Flagg]

Well, the lethal homozygous yellow issue was mentioned already, and it is supposed to cause death of fetuses prior to birth. Perhaps that had something to fo with her death. If you try again you may want to avoidf breeding 2 yellow or fawn or red mice together.

I'm sorry about your mouse Lore, she was pretty.

But if it's homozygous lethal, I imagine that a fetus would have never developed as it probably would have killed the embryo.

The male is Fawn/white marbled, the 2 remaining females, 1 is black the other is grey with red eyes.... will I have genetic issues with either of those??? I don't quite understand the idea behind the fact that the female was fawn and male fawn and white would cause lethal issues... :shrugs:

No you shouldn't have genetic issues with the others. But any fawn or marked fawn offspring should not be bred together or to the male fawn father.

Genetically, the fawn and white male is still fawn, but with markings, which are controlled by a different gene. Just like how a blue hooded rat is still genetically blue, even though it is mostly white.

Thank You for the info! :cheers: Sheesh, I had no idea breeding mice would be so complicated :headbang:
Just my luck I pick the kinds with the death card.

I read somewhere that the regular old white mouse was the hardiest, and long lived. :shrugs:

Well, there's no telling why the female died, I just offered a guess. From what I've read the lethal yellow gene causes the death of homozygous yellow embryos or perhaps fetuses while still in the womb. I've heard nothing about it affecting the pregnant female. Still not a good idea to breed 2 yellows though, for no other reason than you'd lose about 1/4 of every potential litter.

As for albino mice being hardier, I don't know. I think it depends more on the strain they come from than anything else. Albino lab mice are selectively bred for thousands of generations in labs for specific traits, such as Swiss-Websters having huge litters. I wish I could find some of those.

I currently have a couple albino males in 2 of my colonies, they don't seem to breed any differently than the other males, including some fawn males and fawn females. My best breeder female currently is a fawn female with a white stripe. The male is a grey rex or longhair.

Maybe it is possible that she had some sort of cancer? From what I understand mice and rats are very prone to tumors. And in the pictures she does look a lot bigger on one side than the other. :shrugs: I had a pet rat once who suddenly developed a large belly like she was pregnant and then it started getting larger and larger on the left side. I knew she wasn't pregnant as the only other rat she had for company was another female. I had her put to sleep before the tumor got too big. It could be a possibility.

Funny thing is I was going to give up on them and had my mother in law (who loves mice) come over to take the 2 females home for her daughter, and I lifted the hut to get the black one out... and :bang:

she had a litter of 5 pinks
