11. Thus novel genes flow from either side into the hybrid zone. 12. Female choice can also play a role in hindering gene flow . 13. Population subdivision results from decreased gene flow among different groups in a population. 14. The investigators exclude any significant gene flow between the two islands. 15. Anyway most of the East-West Slavs share only a modest gene flow with Bulgarians. 16. This results in hindered gene flow between populations and ultimately leads to gene isolation. 17. This shows that corridors, yes, do maintain some gene flow . 18. The role of migration in gene flow has also been studied in many species. 19. There is evidence of a minimum 0.5 % Neanderthal gene flow into the Denisovans. 20. Some degree of gene flow is normal, and preserves constellations of genes and genotypes.
