The number was further increased to test the possible effects of different color- morph pairings. The original six grafts were sufficient to show a clear-cut response in many of the graft combi- nations. The graft and regeneration experiments were designed to provide several types of information. The autograft ex- periments tested rates of tissue and skeletal fusion and the importance of cut versus uncut surfaces. Further, these experiments compared reactions between sections with mouths and sections without mouths. The allograft/iso- graft experiments were designed to provide information on histocompatibility reactions. They also allowed us to test the hypothesis that all identical color-morphs from the same aggregation are clone-mates, whereas corals taken from different reefs are allogeneic, even if they are of the same color-morph. Regeneration experiments Coralla were cut into sections with mouths and without mouths and with multiple cuts as shown in Figure 1. Sec- tions were maintained in the continuous-flow microcosm aquaria on plastic mesh racks. During the 7-month re- generation period, we examined the fragments and noted the number and location of new mouths. Autograft s Given a single corallum, four grafting orientations were of interest to us (Fig. 2, top). The first was a cut directly across the mouth region with subsequent regrafting in the same orientation. The second was a cut across the cor- allum outside of the mouth region with grafting in the original orientation. The third type of autograft was similar to the second, but w
