Assessing Postzygotic Isolation Using Zygotic Disequilibria in Natural Hybrid Zones
Figure 6
Effects of linkage distance on the maximum or minimum zygotic LDs and the maximum composite digenic LD in an ecological zone: a. the maximum or minimum LDs at the left side (x<0); b. the allele frequencies at the positions of the maximum or minimum LDs at the left side (x<0); c. the maximum or minimum LDs at the right side (x>0); d. the allele frequencies at the positions of the maximum or minimum LDs at the right side (x>0).
Results are obtained from the analytical model. Parameters are the migration rate of pollen = 0.02 and seeds
= 0.01, the relative selection intensity
= 1.0, and the selection coefficient s1 = s2 = 0.02.
