Skeletal variations of the seventh cervical vertebrae in the mouse with special reference to the foramina transversaria and the accessory foramina.
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.
