title: [Unusual Gm-haplotypes possibly due to crossing over].
abstract: Four cases are introduced with unusual Gm-haplotypes. Their possible origin is discussed as being either intra- and intergenic or unequal cross over. The last case shows deletions of either y1 or y3 -cistrons due to unequal cross over.
