Abstract:

The grasshopper Leptysma argentina possesses a highly polymorphic karyotype which suggests that the species is undergoing a period of intensive chromosomal restructuration and evolution. The two populations studied in this work showed: (1) Polymorphism for a centric fusion between two telocentric autosomes; (2) Polymorphism for an interstitial supernumerary segment in the smallest autosome; (3) Presence of a proximal supernumerary segment in the second smallest autosome; (4) Polymorphism for a B-chromosome; (5) Heterozygosity for a complex spontaneous translocation between autosomes; (6) At least two centric shifts in two pairs of autosomes. Another interesting feature of the cytogenetics of these populations was the occurrence, in a relatively high frequency, of dicentric bridges and acentric fragments in Anaphase I probably due to errors in crossing-over. © 1984 Dr W.
