Brother and sister.
I would be grateful for information about this mutation. Maybe this is an intrauterine ugliness?

Perhaps, here bad photos. At these mice one ear "hangs".
Thank you in advance for your opinions.

I don't know what that is.

But it happens I just had one baby like that in a litter, the left ear was set much lower than normal, below eye level. I culled the baby due to it being smaller than its littermates and only after that I noticed this defect.

I wonder, is it always the left ear...?

Is the face otherwise symmetrical except the ears?

I had one black female maybe 8 years ago with an ear like that. My friend took it as a pet and it lived a normal life about 1,5 years long.

I know this is a very old thread indeed, but the pics fit the description of a spontaneous mutation called "Ear askew", as it's the one known ear gene both can make just one or both two ears loop AND doesn't cause other deformities. The problem is, it's a dominant...

Another possibly fitting, recessive, with few other problems caused AND a spontaneous mutation would be H6 homeobox 1; misplaced ears, Hmx1^mpe - which makes "unusually large or abnormally oriented ear lobes". With show type, the unusually large is already there.
