As test statistics for asexuality, we utilized the presence of duplicated multilocus genotypes and maximum deviation from random mating (F IS ) (53 –55). The ratio that is genotype-to-individualG N ratio) had been used to recognize multilocus genotypes (55) (Table S1). Individually developed lineages that are asexualclones) originating from split intimate activities had been distinguished from somewhat different multilocus genotypes that diversified through accumulation of mutations or scoring mistakes by determining the likelih d, p sex , after the methodology outlined in ref. 34 and applied in GENCLONE 2.0 (56). The observed and expected heterozygosity for every single lineage that is clonal57), the percentage of clonal genotypes in a populace, F data, and AMOVA had been determined in GENALEX 6 (58) and Genetic Data review (59). To show the r t population-genetic structure of intimate and asexual populations, we used the multivariate analytical practices (60 –62) NMDS, principal component analysis, and DAPC, as implemented in PERMAP (63), GENALEX (58), and SYSTAT (Systat Software).
We carried out analyses of two distinct datasets first, a dataset that is global included 84 M. ingroup taxa, 32 of them M. smithii, and 87 outgroup taxa. The recently described parasite that is social castrator (64) had not been included. The positioning contained 2,319 bp of protein-coding (exon) sequences of three single-copy nuclear genes and another gene that is mitochondrial had been divided in to 10 partitions. 2nd, we carried out a regional analysis of 41 M. smithii taxa representing one person from all the genotyped populations (Table S5). We obtained 1,515 bp of three genes that are mitochondrial split the positioning into two partitions (Table S6). Constrained topologies had been calculated Bayesian that is using and analyses, and variations in the likelih ds of constrained versus unconstrained topologies had been assessed making use of Bayes facets (65 –67). All ingroup series information had been produced with this research (Table S5). Best-fit types of series development had been chosen for every single partition beneath the Akaike information criterion (68) and hierarchical ratio that is likelih d as determined in MODELTEST v3.7 (69) (Table S6). We carried out partitioned Bayesian analyses utilizing MrBayes v3.1.2 (70). Burn-in and convergence had been assessed utilizing Tracer v1.5 (71). Partitioned ML analyses had been carried away in GARLI 0.97.r737 (72).
We utilized a Bayesian relaxed clock uncorrelated lognormal approach implemented when you l k at the system BEAST v1.4.8 with a Yule process due to the fact tree prior (73 –75). The source node was handed a age that is normal circulation (suggest = 73.5, SD = 4.5), following methodology described in ref. 76. Centered on fossil information, lognormal age previous distributions had been assigned to 3 interior nodes, as outlined in ref. 35. For lots more information on analyses and outcomes, see SI Materials and practices and Tables S1–S8.
