The shapes of the first two thoracic vertebrae of F1 mice produced by crossing BALB/c and CBA inbred strains have been examined at 25-60 days by Fourier analysis. The greatest shape change during this period is between 25 and 30 days and is related to the finalisation of the form of the neural arch and spinous process. Between 30 and 60 days there is continued linear shape change not associated with further increase in vertebral area, and probably due to a constant pattern of localised shape changes. Both vertebrae and both sexes behave similarly.
通过傅里叶分析，对BALB/c和CBA近交系杂交产生的F1代小鼠的前两节胸椎在25至60日龄时的形态进行了检查。在此期间，最大的形态变化发生在25至30日龄之间，与神经弓和棘突形态的最终确定有关。在30至60日龄之间，存在持续的线性形态变化，这与椎体面积的进一步增加无关，可能是由于局部形态变化的恒定模式所致。两个椎骨以及雌雄两性的表现相似。
