Mouse birthday pictures

My SO and I realized that we couldn't let our baby mice's one-month birthday pass without some pictures, so we had a photo shoot the day after their birthday. We've also finished renaming the mice, so I've also included their new names. Click on any of the small images to see a larger version.

Genie - 1 month old
Genie says hi.

Athos - 1 month old Athos - 1 month old Athos - 1 month old
Athos, also known as Ace.

D'Artagnan - 1 month old
D'Artagnan, also known as Deuce.

Genie - 1 month old Genie - 1 month old
Genie, the one mouse whose name hasn't changed. On the left you can see her name-inspiring pattern, and on the right Genie is playing her favorite game of "What's between these two fingers?"

Meryl - 1 month old Meryl - 1 month old
Meryl, formerly known as Narrow Stripey.

Tomoyo - 1 month old
Tomoyo, formerly known as Wide Stripey.

Vash - 1 month old Vash - 1 month old
Vash, formerly known as Runt.

Do you know of any good sources detailing the regulatory mechanisms of these reproductive behaviors?,/i>

I'm afraid not. My research is in mouse genetics, so my interest in their reproductive habits has been practical and mostly learned through watching our colony.

You might be able to get some pointers to relevant literature by contacting the Jackson Laboratory
http://www.jax.org. I think there is a contact email address for general questions. They have online versions of a couple of books on mouse genetics (http://www.informatics.jax.org/mgihome//resources/resources.shtml), but I don't see anything on reproduction. The book on coat color might be interesting, given the interesting black and white color of your mice.

Thanks for the details, Nick! We separated the boys and girls this past weekend (just before they hit five weeks) since we really didn't want our colony to "crank up".

It sounds like you're quite on top of mouse reproduction. Do you know of any good sources detailing the regulatory mechanisms of these reproductive behaviors? I've read a bit about oxytocin, estrogen, and testosterone in rats; is it the same in mice?

So, have you separated the boys from the girls yet? The boys will be sexually mature in a couple of weeks, and if they have contact with a mature female (e.g. Mom), they will start to fight. The females will be mature a week or two later than the males, and then your colony will really crank up. Females go into estrus immediately after delivering pups, so they can deliver a new litter as soon as the old one is weaned.
