Dark symbols represent monogamy females, while open symbols represent control females. Here, the females were continuously housed with control males. Two replicates (A, B) of each were performed. (Holland, B., and W. R. Rice. 1999. Experimental removal of sexual selection reverses intersexual antagonistic coevolution and removes a reproductive load.

How does survivorship of the monogamy females compare to that of the control females? Question 9. What can you infer about female resistance to toxic effects of male courting and/or seminal fluid chemicals during the evolution of monogamy? here to searchExplanation / Answer
8) it is evident that the females which were forced to observe monogamy died at a faster rate (as observed by the slope of the graph). Compared to the control females less number of females, at a given age, survived in case of monogamous females.
9)mating with different male partners (polygamy) expose females to toxic chemicals at a higher probability as opposed to when courted with only 1 make(monogamy). Hence animals evolved to be monogamous thereby being more resistant towards these harmful chemicals.
