Figure 6

Model simulation of a single GM central field among over 1,300 conventional fields. (a) Shows the initial map with centre field (circled) (b) Shows the results of cross-pollination rates of the fields. There are some conventional fields that do not receive any GM input even though they occur in close association with the GM field, due to the effect of different sowing dates, and the fact that pollination times do not overlap. Random processes involved in pollen movement are incorporated in the model.
