The use of molecular techniques for parentage analysis has been a booming science over decade. most important technological breakthrough was the introduction microsatellite markers to ecology, an advance that accompanied by proliferation and refinement statistical data. Over last several years, we have seen steady progress in number areas related analysis, prospects successful studies continue improve. Here, provide updated guide scientists interested embarking on natural or artificial...
The G-matrix summarizes the inheritance of multiple, phenotypic traits. stability and evolution this matrix are important issues because they affect our ability to predict how traits evolve by selection drift. Despite centrality these issues, comparative, experimental, analytical approaches understanding have met with limited success. Nevertheless, empirical studies often find that certain structural features remarkably constant, suggesting persistent regimes or other factors promote...
Abstract Large groups of related progeny, as can be collected from discrete egg masses or fruits, present excellent opportunities for parentage analysis by allowing the reconstruction parental genotypes. Current techniques genotypic require knowledge at least one genotype. Here, I a new computer program that reconstructs genotypes when no parents are known, provided progeny array contains only full and half siblings. The prospects successfully reconstructing such arrays with unknown nearly...
Abstract. Quantitative genetics theory provides a framework that predicts the effects of selection on phenotype consisting suite complex traits. However, ability existing to reconstruct history or predict future trajectory evolution depends upon evolutionary dynamics genetic variance-covariance matrix (G-matrix). Thus, central focus emerging field comparative quantitative is G-matrix. Existing analytical reveals little about G, because problem too be mathematically tractable. As first step...
As a conspicuous evolutionary mechanism, sexual selection has received much attention from theorists and empiricists. Although the importance of mating system to long been appreciated, precise relationship remains obscure. In classic experimental study based on parentage assessment using visible genetic markers, more than 50 years ago A. J. Bateman proposed that cause in Drosophila is 'the stronger correlation, males (relative females), between number mates fertility (number progeny)'. Half...
Evolvability is a key characteristic of any evolving system, and the concept evolvability serves as unifying theme in wide range disciplines related to evolutionary theory. The field quantitative genetics provides framework for exploration with promise produce insights global importance. With respect biological systems, parameters most relevant are G‐matrix, which describes standing additive genetic variances covariances suite traits, M‐matrix, effects new mutations on covariances. A...
Abstract In quantitative genetics, the genetic architecture of traits, described in terms variances and covariances, plays a major role determining trajectory evolutionary change. Hence, variance-covariance matrix (G-matrix) is critical component modern genetics theory. Considerable debate has surrounded issue G-matrix constancy because unstable G-matrices provide difficulties for inference. Empirical studies analytical theory have not resolved debate. Here we present results stochastic...
The characterization of patterns multiple mating is a major facet molecular ecology and paramount to understanding the evolution behaviours associated with parental care mate choice. Over last 15 years, fishes have been particularly well studied respect maternity paternity thanks widespread application microsatellite markers. present review focusses on impressive literature genetic parentage in fishes. In studies natural populations, we find that extremely common across fish species, whereas...
Evolutionary biologists have developed several indices, such as selection gradients (β) and the opportunity for sexual (Is), to quantify actual and/or potential strength of acting in natural or experimental populations. In a recent paper, Klug et al. (J. Evol. Biol.23, 2010, 447) contend that are only legitimate metric quantifying selection. They argue Is similar mating-system-based metrics provide unpredictable results, which may be uncorrelated with on trait, should therefore abandoned. We...
The FST-heterozygosity outlier approach has been a popular method for identifying loci under balancing and positive selection since Beaumont Nichols first proposed it in 1996 recommended its use studies sampling large number of independent populations (at least 10). Since then, their program FDIST2 user-friendly optimized datasets, LOSITAN, have used widely the population genetics literature, often without requisite samples. We observed empirical datasets whose distributions could not be...
Evolutionary origins of derived morphologies ultimately stem from changes in protein structure, gene regulation, and content. A well-assembled, annotated reference genome is a central resource for pursuing these molecular phenomena underlying phenotypic evolution. We explored the Gulf pipefish (Syngnathus scovelli), which belongs to family Syngnathidae (pipefishes, seahorses, seadragons). These fishes have dramatically bodies remarkable novelty among vertebrates, male brood pouch. produce...
Alternative mating strategies are common in nature and generally thought to increase the intensity of sexual selection. However, cuckoldry can theoretically decrease opportunity for selection, particularly highly polygamous species. We address here influence sneaking (fertilization thievery) on selection sand goby Pomatoschistus minutus , a marine fish species which males build defend nests. Our microsatellite-based analysis system natural population shows high rates multiple by males....
In pipefishes and seahorses (family Syngnathidae), the males provide all postzygotic care of offspring by brooding embryos on their ventral surfaces. some species, this phenomenon male "egnancy" results in a reversal usual direction sexual selection, such that females compete more than for access to mates, secondary characteristics evolve females. Thus syngnathids can critical tests theories related evolution sex differences selection. Microsatellite-based studies genetic mating systems...
Highly variable microsatellite loci were employed to study the mating system of sexually dimorphic Gulf pipefish Syngnathus scovelli . In this species, like others in family Syngnathidae, ‘pregnant’ males provide all parental care. collected from one locale northern Mexico, and internally carried broods 40 pregnant analysed genetically. By comparing multilocus fingerprints for inferred mothers against expected genotypic distributions population sample, it was determined that: (i) only male...
