allotypically

Furthermore, to the extent that the formal genetics of allorecognition permit allotypically distinct conspecifics to fuse, the reliability of allorecognition-based analyses of clonal and kin structure in natural populations is compromised (reviewed in Grosberg 1988).

At first sight, this result appears to be counterintuitive, because on average half sibs should be more allotypically distinct from one another than full sibs; thus, there should be more, rather than fewer, unique compatibility types.
