Title Benefits of polyandry data
Downloaded 6 times
Description This Excel file contains data on the 40 field-collected Onthophagus taurus females that were used to estimate rates of multiple mating and patterns of sperm utilization. Column descriptions: PW = prothorax width (in mm); Larvae = number of larvae produced by each female; Min_sires = minimum number of sires (based on GERUD); Standardized_skew = standardized paternity skew, calculated as: (Corrected paternity skew – minimum skew) / (Range); Skew_average = Average paternity skew based on the 50 most likely minimum father-solutions generated by GERUD; Corrected_skew = Average paternity skew corrected for sampling error; Corr_max_skew = Maximum possible value of skew for that female (given the observed number of fathers and clutch size), corrected for sample size Corr_min_skew = Minimum possible value of skew for that female (given the observed number of fathers and clutch size), corrected for sample size; Range = range of possible values of skew, calculated as: Corr_max_skew – Corr_min_skew; Columns M-R are used to manually calculate maximum possible value of skew for that female (given the observed number of fathers and clutch size); Columns S-X are used to manually calculate minimum possible value of skew for that female (given the observed number of fathers and clutch size)

Title Simulations for corrected paternity skew
Downloaded 3 times
Description This file contains the R code for generating hypothetical clutches in order to test whether our estimates of paternity skew were significantly different from a null distribution in which males have equal siring probability (accounting for sampling error in the number of offspring and sires). The script also reports P-values and null estimates of skew for each of the females used in this study (excluding the five females that produced offspring from a single sire).
