Abstract
Karyotypic analysis of 67 individuals of a Mediterranean population of G. paganellus has revealed three new karyomorphs: D2F′1, (2n = 45, NF = 46), F2F′1, (2n = 45, NF = 48), D1F1F′1, (2n = 45, NF = 47), in addition to the seven previously reported by Thode et al. (1985). The C-banding pattern and the meiotic configurations clearly show that the mechanism involved is a new centromeric fusion. The high level of intra-individual variability for this rearrangement suggests a possible origin within this population. The involvements of this fusion in the polymorphism of G. paganellus are discussed mainly in comparison with another centromeric fusion.
