Abstract
In the grasshopper Cibolacris parviceps a chromosomal interchange is described which considerably raises the chiasma frequency in all the chromosomes, including the interchange itself. Both of the chromosomes involved in the interchange have pronounced heterochromatic regions and the possible role of heterochromatin in altering recombination is discussed.
