“…The number of alleles found at Y chromosome (19 alleles) was similar to the average for autosomal loci (20.28 averaged over eight autosomal loci, min: 8 and max: 40) and lower than the number of observed haplotypes for mtDNA (34 haplotypes). These results have parallels in studies of humans (Hurles and Jobling 2001; Kayser et al 2004) and baboons (Lawson Handley et al 2006b), where microsatellite diversity or mutation rate are similar between the Y chromosome and autosomes.…”

“…However, although there has been a large interest in using the Y chromosome in combination with the mtDNA or autosomal markers for resolving phylogenetic or phylogeographic issues (Braendli et al 2005; Hellborg et al 2005; Roca et al 2005; Lawson Handley et al 2006a; Yannic et al 2008a; Vega et al 2010; McDevitt et al 2011), much fewer studies have used information from the Y chromosome to explore sex‐linked differences in the microevolutionary forces shaping the fine‐scale genetic structure of populations. This is mostly explained by the lower polymorphism of the Y chromosome compared to other regions of the genome, which makes it difficult to find sufficiently variable markers for most species (International SNP Map Working Group 2001; Hellborg and Ellegren 2004; Lawson Handley et al 2006b). Studies focusing on humans (Hammer 1995; Seielstad et al 1998; Hammer et al 2003) or other primates (Eriksson et al 2006; Hammond et al 2006; Douadi et al 2007; Guschanski et al 2008) are notable exceptions due to the efforts devoted to human genetics (but see also, Flagstad et al 2003; Musiani et al 2007; Sacks et al 2008 for recent results in canids).…”

Scale-Specific Sex-Biased Dispersal in the Valais Shrew Unveiled by Genetic Variation on the Y Chromosome, Autosomes, and Mitochondrial Dna

We investigated sex specificities in the evolutionary processes shaping Y chromosome, autosomes, and mitochondrial DNA patterns of genetic structure in the Valais shrew (Sorex antinorii), a mountain dwelling species with a hierarchical distribution. Both hierarchical analyses of variance and isolation-by-distance analyses revealed patterns of population structure that were not consistent across maternal, paternal, and biparentally inherited markers. Differentiation on a Y microsatellite was lower than expected from the comparison with autosomal microsatellites and mtDNA, and it was mostly due to genetic variance among populations within valleys, whereas the opposite was observed on other markers. In addition, there was no pattern of isolation by distance for the Y, whereas there was strong isolation by distance on mtDNA and autosomes. We use a hierarchical island model of coancestry dynamics to discuss the relative roles of the microevolutionary forces that may induce such patterns. We conclude that sex-biased dispersal is the most important driver of the observed genetic structure, but with an intriguing twist: it seems that dispersal is strongly male biased at large spatial scale, whereas it is mildly biased in favor of females at local scale. These results add to recent reports of scale-specific sex-biased dispersal patterns, and emphasize the usefulness of the Y chromosome in conjunction with mtDNA and autosomes to infer sex specificities.

“…Unfortunately, we failed to find informative, polymorphic loci when screening several Y-chromosomal markers upon initiation of this study. An extremely low level of diversity on the Y-chromosome has also been described in hamadryas baboons [Lawson Handley et al, 2006 ; Städele et al, 2015 ] and is a common problem in mammalian non-model organisms [Greminger et al, 2010 ]. Still, on average, females appear to migrate more often and/or further away than males in this population of Guinea baboons.…”

Sex differences in philopatry and dispersal have important consequences on the genetic structure of populations, social groups, and social relationships within groups. Among mammals, male dispersal and female philopatry are most common and closely related taxa typically exhibit similar dispersal patterns. However, among four well-studied species of baboons, only hamadryas baboons exhibit female dispersal, thus differing from their congenerics, which show female philopatry and close-knit female social relationships. Until recently, knowledge of the Guinea baboon social system and dispersal pattern remained sparse. Previous observations suggested that the high degree of tolerance observed among male Guinea baboons could be due to kinship. This led us to hypothesize that this species exhibits male philopatry and female dispersal, conforming to the hamadryas pattern. We genotyped 165 individuals from five localities in the Niokolo-Koba National Park, Senegal, at 14 autosomal microsatellite loci and sequenced a fragment of the mitochondrial hypervariable region I (HVRI) of 55 individuals. We found evidence for higher population structuring in males than in females, as expected if males are the more philopatric sex. A comparison of relatedness between male–male and female–female dyads within and among communities did not yield conclusive results. HVRI diversity within communities was high and did not differ between the sexes, also suggesting female gene flow. Our study is the first comprehensive analysis of the genetic population structure in Guinea baboons and provides evidence for female-biased dispersal in this species. In conjunction with their multilevel social organization, this finding parallels the observations for human hunter-gatherers and strengthens baboons as an intriguing model to elucidate the processes that shaped the highly cooperative societies of Homo.

“…Finally, this method obviously relies on characterizing informative sex‐specific markers, and relative lack of variability on the Y chromosome may be a limiting factor here (Hellborg & Ellegren 2004; Hammond et al . 2006; Lawson Handley et al . 2006a, b).…”

Sex-biased dispersal is an almost ubiquitous feature of mammalian life history, but the evolutionary causes behind these patterns still require much clarification. A quarter of a century since the publication of seminal papers describing general patterns of sex-biased dispersal in both mammals and birds, we review the advances in our theoretical understanding of the evolutionary causes of sex-biased dispersal, and those in statistical genetics that enable us to test hypotheses and measure dispersal in natural populations. We use mammalian examples to illustrate patterns and proximate causes of sex-biased dispersal, because by far the most data are available and because they exhibit an enormous diversity in terms of dispersal strategy, mating and social systems. Recent studies using molecular markers have helped to confirm that sex-biased dispersal is widespread among mammals and varies widely in direction and intensity, but there is a great need to bridge the gap between genetic information, observational data and theory. A review of mammalian data indicates that the relationship between direction of sex-bias and mating system is not a simple one. The role of social systems emerges as a key factor in determining intensity and direction of dispersal bias, but there is still need for a theoretical framework that can account for the complex interactions between inbreeding avoidance, kin competition and cooperation to explain the impressive diversity of patterns.
