Cumulative density function observed (crosses) and expected (thin line) for the number of matings per male lifetime in the data set. Expected probability distribution was fitted by regression to y = 0.63x−2.01 up to a value of 25 matings, whereas for 26–50 matings, probability was equal to 4 × 10−3, and for 51–200 matings, probability was equal to 2.3 × 10−5.
