Absence of Corpus Callosum, a Hereditary Brain Anomaly of the House Mouse. Preliminary Report

Abstract
In a variety of Mus musculus with rodless retinae, previously described by Keeler, animals were found in which the brain completely lacked the corpus callosum. This absence seems to be a unit character, segregating sharply, and not linked with parted frontals, dominant spotting, or silver. It is not linked to rodless retina, although found in an outcross of that strain.
