I recently bred two broken marked type mice together - mom is black, blazed face, couple small white spots on her back, and a long white spot on her stomach. Dad is a broken marked golden brown, blazed face, zig-zag sort of white lines down his back. They both have black tan in their lines.
She had 9, 3 girls and 6 boys, took it down to 3 girls and 2 boys. They are mostly all tan or broken tan. Some have this odd marking though - it looks like momma mouse's white tummy stripe, in the middle of the tan.
Baby with momma's mark
Baby wiht poor tan marking
Baby with BOTH
The other two babies are broken.
Is this common? I'm not breeding for showing (no shows around here anyway
) so it isn't a big deal that they have big colour faults, but what caused this?
