Key Points
-
Most studies of the genetic basis of mate choice focus on male sexually selected traits and the corresponding female preferences.
-
Male sexually selected traits tend to exhibit multi-component phenotypes. Investigations of the genetic basis of mate choice should therefore not only consider that a number of different types of trait might be under sexual selection, but that each trait could be multidimensional in nature.
-
Genetic studies of mate choice should first determine which male traits are under sexual selection. Mate choice experiments enable the formal analysis of the form of sexual selection operating on male traits.
-
Quantitative genetic analyses of male traits and the female preferences for them have established the presence of genetic variance in these traits in many experimental systems. The genetic analysis of female preferences, however, tends to be more difficult, and the genetic analyses of female preference functions using genetic covariance functions have yet to be conducted.
-
Male sexually selected traits are likely to be influenced by indirect genetic effects as males can change their displays in response to the phenotype, and therefore genotype, of the female being displayed to. Although indirect genetic effects on male sexually selected traits have been identified, the evolutionary implications of their presence have yet to be tested.
-
Caution needs to be applied in experimental studies to ensure that naturally occurring genetic variation in mate choice is the target of investigation. For example, the ability of a mutagenic allele to affect trait expression does not necessarily demonstrate that allelic variation at that locus generates naturally occurring genetic variance in the trait.
-
QTL analyses have successfully identified genomic regions that make large contributions to male traits.
-
Transcriptional profiling experiments are beginning to be used in investigations of mate choice. Making sense of the large number of transcripts that are likely to be involved will be a considerable challenge.
-
The genetic analysis of multiple traits is a key issue for investigations of male sexually selected traits. Combining transcriptional profiling experiments with multivariate quantitative genetic approaches holds considerable promise in addressing the complex nature of phenotypes that are involved in mate choice.
Abstract
The genetic analysis of mate choice is fraught with difficulties. Males produce complex signals and displays that can consist of a combination of acoustic, visual, chemical and behavioural phenotypes. Furthermore, female preferences for these male traits are notoriously difficult to quantify. During mate choice, genes not only affect the phenotypes of the individual they are in, but can influence the expression of traits in other individuals. How can genetic analyses be conducted to encompass this complexity? Tighter integration of classical quantitative genetic approaches with modern genomic technologies promises to advance our understanding of the complex genetic basis of mate choice.
