  text: The grasshopper Podisma pedestris contains two chromosomal races, which differ
    by a Robertsonian fusion between the sex chromosome and an autosome, and which
    meet in a narrow hybrid zone in the Alpes Maritimes. DNA content variation across
    this hybrid zone was investigated by optical densitometry of Feulgen stained spermatids.
    Spermatids from males with the unfused sex chromosome stain more strongly than
    those from males with the fused chromosome. The difference between the karyotypes
    is greater in the centre of the hybrid zone, suggesting that it is not a pleiotropic
    effect of the fusion itself, but is due instead to differences at closely linked
    loci.
