The insemination success of females as a function of the numbers of males and female per cage. The proportion of uninseminated females is plotted as lines representing of the fitted competition model (See materials and methods) at each level of female numbers per cage (See table 2). The mean of observations at each number of males per cage (n = 3) are represented by circles, diamonds and squares for 10, 30 and 100 females per cage, respectively.
