It is shown that a linked cline induces a step in the frequency of a neutral allele, which is proportional to the gradient in neutral allele frequency and to the inverse of the recombination rate. A barrier to dispersal or a local region of low abundance has a similar effect (Nagylaki, 1976). The cline will block the flow of neutral alleles over a region of chromosome roughly 2s/t map units long. However, a slightly advantageous allele will be little affected, and must be very tightly linked to be delayed for long."}],"volume":43,"date_created":"2018-12-11T12:04:33Z","publication_identifier":{"eissn":["1365-2540"],"issn":["0018-067X"]},"month":"12","year":"1979","intvolume":"        43","citation":{"short":"N.H.
