The table below can be used to translate selected proportions to selection intensities. In the table p% is the selected proportion in percentages, and i is the corresponding selection intensity. For selected proportions in between the values mentioned in the table, take the linear approximation of i. For selected proportions larger than 50%, take the i for (1-p) and multiply that i by (1-p)/p. The table is a simplified version from the table published in Falconer and Mackay, 1996.
