title: Skeletal variations of the seventh cervical vertebrae in the mouse with special reference to the foramina transversaria and the accessory foramina.
abstract: The formation of foramina transversaria in the seventh cervical vertebra of CBA and C57BL mice and their offspring is found to behave as if it is determined by a single semi-dominant gene. The accessory foramina of Weber (1950) are investigated in the same material. These foramina are classified into two types and their heredity is evaluated.
