Figure 4. Clines from loci under
no selection (grey) and average hybrid index clines (black), obtained
from 100 replicates in different demographic histories. Each cline is
from a locus from independent replicates. Blue squares are hybrid zones
with m= 0.1. Orange squares are hybrid zones with m= 0.01.
Solid squares are young hybrid zones after 100 generations of admixture.
Open squares are old hybrid zones after 1000 generations of
admixture.
