Nonpaternity and Half-Siblingships as Objective Measures of Extramarital Sex: Mathematical Modeling and Simulations

Figure 4

Consistency between global nonpaternity data and self-reported extramarital sex in Sub-Saharan Africa. Mean and 95% confidence interval of the nonpaternity ratio () over 100 simulations at different values of the fraction of coital acts that are with the spouse, as opposed to an extramarital partner, among married women. The dashed black line shows a typical intermediate value for the nonpaternity ratio per a global review of nonpaternity data [16].
