Although the amount of seed coming from outside the village is low (3%-4%), the cumulative combination over a 10-20 year time horizon, combined with the periodic renewal of seed and trade within the village, can have a sizable impact on the flow of genes.

Finally, the seed questions were asked to the larger sample in order to see if the estimates of the flow of seeds into the village were robust. The question was asked where farmers would look for seed //they needed it.
