Abstract

Austroicetes interioris is polymorphic for pericentric inversions. The three autosomal polymorphisms are considered to be heterotic. In each case the chromosome with the inversion differs from its standard counterpart in the amount of heterochromatin present. Consequently the various karyotypes have appreciable diversity in heterochromatin content. Two of the inversion chromosomes form a terminal association considered to be chiasmate in nature. The resulting quadrivalents favour one particular first metaphase orientation and this causes segregation distortion. The terminal associations and the heterochromatin disparity between the members of each polymorphism are considered to be due to translocations with break points situated in regions of little genetic activity near chromosome tips and causing interchange of telomeres but not of euchromatic segments. Evolutionary implications of such rearrangements are discussed.
