Do favored cuticular hydrocarbon profiles signal fertility? Analysis of Gryllus firmus and Gryllus pennsylvanicus

Previous studies suggest that the cuticular hydrocarbon profiles of Gryllus firmus and G. pennsylvanicus are sexually dimorphic: males have a relatively homogenous and simple profile, whereas females are more variable, and some individuals resemble the profile of males (“male-like” females). Previous studies have shown that males in captivity prefer females with a more male-like profile, mating with them more promptly. Here, we used both species to test whether cuticular hydrocarbons serve as signal of female fertility and whether females with a male-like cuticular hydrocarbon profile mate more often in the field. We report on the number of sires for field-caught females and demonstrate that male-like females are not more fertile and do not mate more often in the wild. We also show that the allocation of sperm does not seem to follow a fair raffle; a few males dominate the brood composition of wild-caught mated females., Field collected previously mated females of two species. Females oviposit in lab. Offpspring are scored with 7 microsatellites to predict number of fathers in a brood (48 offspring per brood). We use COLONY (Jones & Wang, 2010) to calculate number of fathers per brood.  
We test if females with different cuticular hydrocarbon profiles produce a different number of offspring (good genes) or if certain females mate more often in the field., , # Do favored cuticular hydrocarbon profiles signal fertility? Analysis of Gryllus firmus and Gryllus pennsylvanicus

This dataset contains offspring genotypes, Cuticular hydrocarbon calls for all parents and supplementary individuals, allele frequencies used in the Colony program, and results from the Colony program

## Description of the data and file structure

There are five data sheets:

Allele_Frequencies.xlsx: These are allele frequencies used in the Colony analyses for each brood. The allele frequencies were calculated in CERVUS and used as input “known allele frequencies” to increase COLONY’s accuracy

COLONY_Output.xlsx: Results from Colony run. Each species was analyzed with 3 different error rates (each in a separate tab), fathers for each female brood (Female ID) are designated with numbers. The \"Prob (Inc.) refers to the probability that all individuals of a given fullsib family are fullsibs - the lower the probability the higher the change that the fullsibship could be s...,
