Distribution of average number of sires per litter for L-fast populations from simulations restricting L-fast litter sizes to M-slow median litter size of 5. Frequency is the number of times the mean number of sires was observed out of 999 iterations. The red line indicates the observed average number of sires for M-slow litters (1.46 sires per litter). The mean number of simulated L-fast fathers was not significantly different from observed M-slow values (P = 0.136).
