Abstract
Chromosome preparations from 46 specimens of G. paganellus were studied, revealing seven different karyomorphs: D2 (2n=46, NF=46), D1 (2n=47, NF=47), B (2n=48, NF=48), F1 (2n=47, NF=48), F2 (2n=46, NF=48), D1F1 (2n=46, NF=47), I1 (2n=48, NF=49). It is proposed that the mechanisms involved are deletions, fusions and inversions. The meiotic results suggest that the same chromosome pair was engaged in both the fusion and the deletion rearrangements. Intra-individual polymorphism was found in only one specimen. This and the range of karyomorphs suggest that this variation is regularly inherited.
