  - "This paper investigates the dynamic behaviour of hybrid zones which are maintained
    by a balance between dispersal and selection against hybrids. In the first section
    it is shown that a hybrid zone involving a single locus can move in response to
    a selective imbalance between the two homozygotes, and also to variation in population
    density and dispersal rate. It can be trapped by natural barriers, and so an allele
    which is selected against when rare cannot advance, even if it is advantageous
    when common. The continuous model used in deriving these results is shown to be
    a good approximation to the stepping-stone model, provided that the cline contains
    several demes.\r\n\r\nThe effect of stochastic forces on multi-locus hybrid zones
    is then considered. An expression giving the shift in position after an arbitrary
    perturbation in gamete frequency is derived. Using this formula, it is found that
    sampling drift is negligible unless the zone includes few organisms and involves
    few loci. Random variations in population structure are the dominant force, and
    could allow considerable movement in an even environment. However, natural barriers
    can still trap hybrid zones, and so it is likely that they will remain roughly
    where they first formed.@eng"
