In the H-Y incompatible C57BL/6 male to female system, both tail and ear skin grafts were found to persist longer than body (thorax) skin grafts of the same size and shape. Ear skin grafts of long standing did not affect the survival of subsequent body skin grafts but, in one case, a long-term tail skin graft prolonged the survival of a subsequent body skin gratf, both transplants persisting throughout the life of the host. Whereas ear skin grafts from which cartilage was removed were invariably rejected, several ear skin grafts with cartilage intact survived permanently.
在H-Y不相容的C57BL/6雄性对雌性系统中，发现尾巴和耳部皮肤移植片比相同大小和形状的身体（胸部）皮肤移植片存活时间更长。长期存活的耳部皮肤移植片不影响随后身体皮肤移植片的存活，但在一个案例中，一个长期存活的尾巴皮肤移植片延长了随后身体皮肤移植片的存活时间，两个移植片在宿主的整个生命过程中都持续存活。去除软骨的耳部皮肤移植片总是被排斥，而几个软骨完整的耳部皮肤移植片永久存活。
