In sexually dimorphic species, partners can assess heritable mate quality by analyzing costly sexual ornaments in terms of their dimension and possibly of their symmetry. In vertebrates an important aspect of genetic quality is the efficiency of the immune system, and in particular the Major Histocompatibility Complex (MHC). If ornaments are honest advertisements of pathogen resistance (good genes), in line with the Hamilton-Zuk hypothesis, a correlation between ornament expression and MHC… Expand
Male transmission ratio distortion supports MHC-linked cryptic female choice in the lesser kestrel (Aves: Falconidae)
TLDR
The inheritance of alleles across a highly polymorphic MHC class II B gene in a socially monogamous raptor, the lesser kestrel Falco naumanni, is investigated and one of the very few studies supporting the MHC-based female cryptic choice in birds is supported and opens inspiring lines of research. Expand
MHC genotype predicts mate choice in the ring‐necked pheasant Phasianus colchicus
TLDR
MHC‐based mating preferences in the ring‐necked pheasant do not seem to be mediated by ornaments’ expression and may have evolved mainly to reduce the costs of high heterozygosity at MHC loci for the progeny, such as increased risk of autoimmune diseases or disruption of coadapted gene pools. Expand
Occurrence of extra‐pair paternity is connected to social male's MHC‐variability in the scarlet rosefinch Carpodacus erythrinus
TLDR
This work investigated the impact of MHC class I variability on within-pair and extra-pair fertilisation success in a wild population of a socially monogamous passerine bird with considerable rates of extra- Pair paternity, the scarlet rosefinch Carpodacus erythrinus and found some support for the ‘good-genes-as-heterozygosity model’.

Mate choice for major histocompatibility complex (MHC) complementarity in the Yellow-rumped Flycatcher (Ficedula zanthopygia)
Background Genes of the major histocompatibility complex (MHC) are an important component of the vertebrate immune system and play a significant role in mate choice in animal populations. However,Expand
Egg testosterone affects wattle color and trait covariation in the ring-necked pheasant
TLDR
This study injected testosterone in egg albumen of captive ring-necked pheasant eggs, and found that control males had redder wattles than males from T-injected eggs, suggesting that attractiveness and reproductive success of the offspring might vary depending on maternal transfer of T to the eggs. Expand
Mutual Wattle Ornaments in the South Island Saddleback (Philesturnus carunculatus) Function as Armaments
TLDR
The markedly similar use of wattles by both males and females in visual displays as a response to territorial intrusions supports the hypothesis that these elaborate structures function in part as armaments. Expand
MHC Class IIB Exon 2 Polymorphism in the Grey Partridge (Perdix perdix) Is Shaped by Selection, Recombination and Gene Conversion
TLDR
The results indicate that the Grey partridge MHCIIB is comparable to most other galliforms in terms of copy number and population polymorphism. Expand
Effects of egg testosterone on female mate choice and male sexual behavior in the pheasant
TLDR
Results demonstrate that variation in the early hormonal environment set up by mothers affects sexual behavior of the offspring, which might translate into fitness differences. Expand
Evaluation of two approaches to genotyping major histocompatibility complex class I in a passerine—CE‐SSCP and 454 pyrosequencing
TLDR
In systems with highly duplicated MHC, 454 provides more reliable information on individual diversity than CE‐SSCP, and numbers of alleles detected by both methods are significantly correlated, although the correlation is weak. Expand
The role of bare parts in avian signaling
TLDR
More careful and extensive characterization of bare-part coloration in a wider range of species is urged because of its potential to advance the understanding of signal function and constraints, with particular reference to the role of dynamic color signals and the evolution of multiple ornamentation.

Mate Choice, Male Condition‐Dependent Ornamentation and MHC in the Pheasant
TLDR
Data indicate that polymorphic genes with a central role in immune recognition can be associated with viability and the expression of a condition-dependent intersexually selected male trait, thus supporting essential parts of the Hamilton and Zuk model. Expand
MHC genotype and male ornamentation: genetic evidence for the Hamilton-Zuk model
TLDR
These are the first data that directly support a ‘good genes’ hypothesis by Hamilton and Zuk predicting that females discriminate among males on the basis of secondary sexual characters in order to pass on genes for disease resistance that improve fitness in their offspring. Expand
MAJOR-HISTOCOMPATIBILITY-COMPLEX-ASSOCIATED VARIATION IN SECONDARY SEXUAL TRAITS OF WHITE-TAILED DEER (ODOCOILEUS VIRGINIANUS): EVIDENCE FOR GOOD-GENES ADVERTISEMENT
TLDR
Observations provide support for the hypothesis that antler development in white-tailed deer is an honest signal of quality, suggesting that certain MHC characteristics may help deer cope with stresses related to breeding activity. Expand
Multiple ornaments are positively related to male survival in the common pheasant
TLDR
Male survivors had larger multiple ornaments, regardless of age, than males that were killed by predators but survival selection on wing length and body weight was nonsignificant, showing that selection on male ornament was not the result of selection on correlated traits. Expand
The scent of genetic compatibility: Sexual selection and the major histocompatibility complex
TLDR
The evidence for MHC-dependent mating preferences from recent studies is reviewed, including studies on the underlying olfactory mechanisms and evolutionary functions, and other ways that MHC genes might influence sexual selection are discussed. Expand
The Major Histocompatibility Complex, Sexual Selection, and Mate Choice
TLDR
MHC ligand peptides may be the natural “perfume” that reveals a potential partner's MHC genetics probably in all vertebrates and maximizes resistance to ever-changing infectious diseases. Expand
Is the peacock’s train an honest signal of genetic quality at the major histocompatibility complex?
TLDR
It is demonstrated via a captive breeding experiment that train length of adult males reflects genetic diversity at the MHC while controlling for genome‐wide diversity and that peahens lay more, and larger, eggs for Males with a more diverse MHC, but not for males with longer trains. Expand
Maintenance of genetic variation in sexual ornaments: a review of the mechanisms
TLDR
It is discussed how the traditional ways of testing for genetic benefits can usefully be supplemented by tests detecting benefits resulting from specific mechanisms maintaining VA in sexual ornaments. Expand
Evolution of MHC class IIB in the genome of wild and ornamental guppies, Poecilia reticulata
TLDR
It is suggested that the same allele is fixed at duplicated MHC DAB loci owing to gene conversion, and the number of loci in the ornamental strains has contracted during >100 generations in captivity, a hypothesis consistent with the accordion model of MHC evolution. Expand
Individual MHC class I and MHC class IIB diversities are associated with male and female reproductive traits in the three‐spined stickleback
TLDR
With wild‐caught three‐spined sticklebacks (Gasterosteus aculeatus), the first study to relate individual reproductive parameters to both MHC class I and II diversities is conducted, suggesting that if an allele is currently not part of the optimum, it had not been propagated by choosy females.
