The results of grafts performed in the larva of the beetle Tenebrio molitor reveal that the position at which certain adult muscle attachments form is specified by a regulative, rather than a mosaic, mechanism. The results of grafts involving the rotation of squares of integument through 180 degrees or 90 degrees, or the antero-posterior transposition of two adjacent rectangles of integument, show that the site of muscle attachments in the antero-posterior axis of an abdominal sternite is specified by an epidermal segmental gradient of positional information. This gradient is presumed to be identical to the gradient which specifies cuticular patterns in this insect. There is a good correlation between the effect of grafts on adult muscle morphology and cuticular patterns.
在黄粉虫幼虫身上进行移植实验的结果表明，某些成虫肌肉附着点形成的位置是由一种调节机制而非镶嵌机制决定的。涉及将体壁方块旋转180度或90度，或两个相邻体壁矩形前后换位的移植实验结果显示，腹部腹板前后轴上肌肉附着点的位置是由表皮节段性位置信息梯度决定的。这种梯度被认为与决定该昆虫表皮图案的梯度相同。移植对成虫肌肉形态和表皮图案的影响之间存在良好的相关性。
