According to a study by Menna Jones, " gene flow appears extensive up to convert", meaning a high assignment rate to source or close neighbour populations "in agreement with movement data.
Change in Pleistocene populations did not involve speciation (the splitting of one species into two): all this time, the geographically distinct populations maintained small amounts of gene flow.
Genetic changes within groups result in increasing incompatibility between the genomes of the two subgroups, thus reducing gene flow between the groups.
Concerns focus on the interaction between GM and other maize varieties in Mexico, and of gene flow into refuges.
At larger scales (convert), gene flow is reduced but there is no evidence for isolation by distance".
Instead, speciation results from the evolution of mechanisms that reduce gene flow between the two populations.
