Measures of male reproductive performance across mating events

The cost of reproduction is well studied in females but only recently have the costs of mating been investigated in males. Research suggests that males allocate resources between subsequent mating events, resulting in differential success across mating bouts. Selection should favor allocation strategies that match the likelihood of successive matings. The complexity of the system, however, suggests that one fixed strategy is unlikely to be universally favored and thus I predict that genetic variation for different allocation strategies will be segregating in natural populations. To test this, I measured several components of reproductive performance in eight inbred genotypes of Drosophila melanogaster across three sequential mating events. As predicted, there was genetic variation in how previous experience affected a male’s reproductive performance for both the proportion of matings that produced offspring and the proportion of offspring sired (P1). Some genotypes had the highest succe..., , , # Measures of male reproductive performance across mating events

## Description of the data and file structure

**\"ExpMatters_R.csv\"**

* GENOTYPE: this is the DGRP Line that the male was from, and corresponds to the genotype in the manuscript
* MATING_EXP: this is the mating experience for that particular male, FIRST, SECOND, THIRD
* REP: the replicate, used to make the ID column
* BLOCK: the block (generation) in which the flies were collected
* ID: the actual individual male, used for repeated measures design
* FEMALE: the genotype of the female (cnbw1 is recessive white-eyed)
* V1W: number of white eyed offspring in Vial 1 (sired by competitor male)
* V1R: number of red eyed offspring in Vial 1 (sired by focal male)
* V2W: number of white eyed offspring in Vial 2 (sired by competitor male)
* V2R: number o...
