Caption

Rump-white is a dominant lethal mutation from which homozygotes die in utero around embryonic day 9.5. From the earliest developmental stage assessed, E7.5, smaller size is detectable in Rw/Rw embryos. Rump-white heterozygotes have hypopigmentation in the front digits and hindquarters including white hindlegs, white tail with the tip often pigmented, and a variable degree of white in the sacral and lumbar regions with the ventral area more consistently affected than the dorsal area.
