“…The frequency of the other two male types in populations (satellite and resident males) is consistent with a single-locus, two-allele autosomal genetic polymorphism (Lank et al 1995). Faeders may represent the expected 1% of Ruffs homozygous for the satellite allele (Lank et al 1995), a genotype undisclosed in the single captive-breeding study so far.…”

“…As suggested by van Rhijn (1985), faeders may represent the ancestral male type, but their relatively large testes suggest that currently they behave as 'sneakers' (Taborsky 1994).

“…When male-male competition becomes so severe that one phenotypic class of males is excluded almost entirely from mating, frequency-dependent selection is thought to favour the development of alternative male mating strategies, such as "sneakers", "female mimics" or less aggressive (satellite) males (Lank et al 1995, Sinervo and Lively 1996, Shuster and Sassaman 1997. Such genetic polymorphisms in males, driven by frequency-dependent matecompetition could be expressed as size differences between males (Gross 1985, Shuster andSassaman 1997) or as differences in signalling traits (e. g. colour) and/or behaviour (Lank et al 1995, Sinervo andLively 1996).…”

Heritable and visually detectable polymorphisms, such as trophic polymorphisms, ecotypes, or colour morphs, have become classical model systems among ecological geneticists and evolutionary biologists. The relatively simple genetic basis of many such polymorphisms (one or a few loci) makes such species well-suited to study evolutionary processes in natural settings. More recently, polymorphic systems have become popular when studying the early stages of the speciation process and mechanisms facilitating or constraining the evolution of reproductive isolation. Although colour polymorphisms have been studied extensively in the past, we argue that they have been underutilized as model systems of constraints on speciation processes. Colouration traits may function as signalling characters in sexual selection contexts, and the maintenance of colour polymorphisms is often due to frequency-dependent selection.One important issue is why there are so few described cases of female polymorphisms. Here we present a synthetic overview of female sexual polymorphisms, drawing from our previous work on female colour polymorphisms in lizards and damselflies. We argue that female sexual polymorphisms have probably been overlooked in the past, since workers have mainly focused on male-male competition over mates and have not realized the ecological sources of genetic variation in female fitness. Recent experimental evolution studies on fruit flies (Drosophila melanogaster) have demonstrated significant heritable variation among female genotypes in the fitness costs of resistance or tolerance to male mating harassment. In addition, femalefemale competition over resources could also generate genetic variation in female fitness and promote the maintenance of female sexual polymorphisms. Female sexual polymorphisms could subsequently either be maintained as intrapopulational polymorphisms or provide the raw material for the formation of new species.

“…We implanted 112 reeves from this £ock with testosterone immediately following breeding seasons in 1991^1995 (n 10, 33, 32, 21, 31 per season, respectively; 15 reeves were implanted in two di¡erent years). The paternity of 91 of these reeves was known because their mothers had bred in captivity while segregated with a single male (n 82), or was determined by minisatellite DNA ¢ngerprinting of eggs collected in the wild (n 9; Lank et al 1995). Twenty-one implanted reeves, also raised from eggs collected in the wild, had unknown fathers.…”

A balanced polymorphism in male mating behaviour exists in male ru¡s, with no obvious parallel expression in females. Pedigree data of male phenotypes support an autosomal model of inheritance, in contrast to sexlinked inheritance patterns found in other taxa with sex-limited alternative mating strategy polymorphisms. We tested this model by inducing male courtship behaviour in gonad-intact female ru¡s, using subcutaneous testosterone implants that produced physiological concentrations of testosterone. The implants rapidly induced in females both types of male mating behaviour, an increase in body mass typical of pre-breeding males, and the growth of normally male-limited breeding plumage. As predicted under an autosomal model, the distributions of induced male behaviour types in females paralleled those of their brothers and halfbrothers, and were inconsistent with sex-linked models. E¡ects were reversible, and experimental females bred normally in subsequent years. Our results show that genotype-speci¢c male characteristics can be induced by testosterone in female adults that have presumably not undergone neural organization for them early in life, showing direct use of genetic information in intra-and intersexual di¡erentiation.
