The reduction in mean fitness at the centre of a hybridzone is a measure of the total selection acting. Once the data on metacentric frequency was collated for each collection site, characteristics of the hybridzone were determined. In a hybridzone, they therefore contribute to decrease linkage disequilibria as well as the barrier to gene flow imposed by hybrid depression. Such selection of the fitter hybrid genotypes could scatter the clines that make up a hybridzone, invalidating inferences made assuming concordance. We also need to characterize the different t haplotype variants segregating in the natural populations on either side of the hybridzone. Predicting the shape of the selected clines, and hence mean fitness across the hybridzone, is more difficult, because it does depend on the genetic basis of fitness differences. If hybrid fitness were reduced by the separate effects of several independent sets of interacting genes, the average selection coefficient would not change so drastically across the hybridzone. The barrier to gene flow at neutral loci, which is reflected in distortion of neutral clines, is determined by the pattern of mean fitness across the hybridzone (23). Dispersal of individual parents leads to the creation of more hybrids within the hybridzone. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license.

Where their ranges meet, the yellowhammer and pine bunting interbreed; the yellowhammer is dominant, and the hybridzone is moving further east.

In a tension zone there is the increased probability of hybridization between species of the separate zones and thus the tension zone may also be a hybridzone.
