  bibo_abstract:
  - Samples were taken from five sites in a transect across the hybrid zone between
    two chromosomal races of the grasshopper Podisma pedestris. Crosses were set up
    between insects from the same population, and between populations spanning the
    zone, and the early viability of the offspring was measured. Hybrids between pure
    populations had reduced viability, and the viability of insects from the middle
    of the zone was still lower, showing that most (87 per cent) of the inviability
    was due to the breakup of coadapated gene complexes. Although the total selection
    acting was strong (log. fitness reduced by S25), it was spread over a region wider
    than the dispersal range (350 m vs. 20 m). Hence, the selection on each locus
    contributing towards the inviability is weak (3 per cent). Many (150) independent
    chromosome segments act cumulatively to produce inviability at this stage in the
    life history. The implications of these findings for models of divergence are
    discussed.@eng
