I have two variegated / lethal white gerbils. I know that, if they have babies that are solid white, or solid white with a small spot, they will most likely get mega colon, and die. Is there anything similar in variegated mice? I know that homozygous is lethal, but in what way? Do they die before birth? Or at some time after?
Lethal White *is* lethal in homozygous form (W/W) but is does not kill in the womb like Ay/Ay and Rw/Rw... W/W mice are generally born with no coloured hairs at all, mostly look like black eyed whites, and don't thrive and generally die before weaning.
I'm assuming it is some sort of deficiency, though I haven't looked into it extensively because its not a variety I ever intend to keep.
I was wondering.
I know from my experience with the gerbils, the white one made it to young adulthood, and then got fat very suddenly, and just keeled over one day. I'm assuming mega colon, and will cull any other solid white babies.
I wish I had variegated mice. . . -grumble grumble-
