| Abstract: | Samples were taken from twenty three Australian mainland populations of the shorthorned grasshopper, Phaulacridium vittatum. Five of these populations were found to be polymorphic for B-chromosomes. The anaphase I segregation of the B-chromosome appeared to be random with respect to the X (contra Jackson and Cheung, 1967). The B-chromosomes did not appear to influence chiasma frequency in the population in which they were found. |
