Abstract
In a population sample of 74 individuals of the grasshopper Stauroderus scalaris a single male proved to be a heterozygous mosaic for an interchange involving unequal segments of the L1 and S8 chromosomes; one third of its testis follicles carried the mutation. Chiasma formation in the S8 failed frequently thus leading to formation of chains of three plus one S8 univalent. Whilst a reduction in chiasma frequency was observed in the long arm of the L1 in all types of multiples, an increase in chiasma frequency of the bivalents not involved in the interchange was observed in cells with chains of three plus one univalent compared to those with multiples of four, so that total cell chiasma frequency remained constant. In all cells carrying the interchange, the orientation of the multiple was consistently non-disjunctional and so is expected to lead to gametic imbalance.
