title: Data from: Direct detection of male quality can facilitate the evolution of female choosiness and indicators of good genes: evolution across a continuum of indicator mechanisms

description: The evolution of mating displays as indicators of male quality has been
 the subject of extensive theoretical and empirical research for over four
 decades. Research has also addressed the evolution of female mate choice
 favoring such indicators. Yet, much debate still exists about whether
 displays can evolve through the indirect benefits of female mate choice.
 Here, we use a population genetic model to investigate how the extent to
 which females can directly detect male quality influences the evolution of
 female choosiness and male displays. We use a continuum framework that
 incorporates indicator mechanisms that are traditionally modelled
 separately. Counter to intuition, we find that intermediate levels of
 direct detection of male quality can facilitate, rather than impede, the
 evolution of female choosiness and male displays in broad regions of this
 continuum. We examine how this evolution is driven by selective forces on
 genetic quality and on the display, and find that direct detection of male
 quality results in stronger indirect selection favoring female choosiness.
 Our results imply that displays maybe more likely to evolve when female
 choosiness has already evolved to discriminate perceptible forms of male
 quality. They also highlight the importance of considering general female
 choosiness, as well as preference, in studies of "good genes".
description: Life cycle loop with
 frequency-dependent cost of mate choiceThis file includes the
 complete life cycle used in the simulations. This particular lifecycle
 includes frequency-dependent cost of choosiness. The simulations are run
 by holding the frequency of the genetic quality alleles constant. The file
 allows users to generate a timeseries plot for given values of
 parameters.Life cycle with
 frequency-Independentcost of mate choiceThis file includes a
 version of the complete life cycle with frequency-INDEPENDENT cost of
 choosiness. Similar to the other life cycle file, the simulations are run
 by holding the frequency of the genetic quality alleles constant. The file
 allows users to generate a timeseries plot for given values of parameters.
 The plot provided is the same as that shown in Figure S5 of the
 manuscript.Derivation of selection
 coefficients and notation used in equations 3 and 4This file includes the
 complete derivation of the selection coefficients used to generate figures
 5 and 6 in the main text of the manuscript. The file uses the notation
 developed by Barton and Turelli (1991; PubMedID 2016044) to separate and
 analyze different components of selection. These are then used to
 calculate the exact strength of selection from different sources in the
