Data for: Global frequency analyses of canine progressive rod-cone degeneration–progressive retinal atrophy and collie eye anomaly using commercial genetic testing data
<p>Hundreds of genetic variants associated with canine traits and disorders have been identified, with commercial tests offered. However, the geographic distributions and changes in allele and genotype frequencies over prolonged, continuous periods of time are lacking. This study utilized a large set of genotypes from dogs tested for the progressive rod-cone degeneration–progressive retinal atrophy (prcd-PRA) G>A missense PRCD variant (n = 86,667) and the collie eye anomaly (CEA)-associated NHEJ1 deletion (n = 33,834) provided by the commercial genetic testing company (Optigen/Wisdom Panel, Mars Petcare Science & Diagnostics). These data were analyzed using the chi-square goodness-of-fit test, time-trend graphical analysis, and regression modeling in order to evaluate how test results changed over time. The results span fifteen years, representing 82 countries and 67 breeds/breed mixes. Both diseases exhibited significant differences in genotype frequencies (p = 2.7 × 10−152 for prcd-PRA and 0.023 for CEA) with opposing graphical trends. Regression modeling showed time progression to significantly affect the odds of a dog being homozygous or heterozygous for either disease, as do variables including breed and breed popularity. This study shows that genetic testing informed breeding decisions to produce fewer affected dogs. However, the presence of dogs homozygous for the disease variant, especially for prcd-PRA, was still observed fourteen years after test availability, potentially due to crosses of unknown carriers. This suggests that genetic testing of dog populations should continue.</p>

Genetic variation for sexual dimorphism in developmental traits in Drosophila melanogaster
<p>Sexual dimorphism in traits of insects during the developmental stages could potentially be the direct or indirect result of sex-specific selection provided that genetic variation for sexual dimorphism is present. We investigated genetic variation in sexual dimorphism in a set of <em>Drosophila melanogaster</em> inbred lines for two traits: egg to adult development time and pupation site preference. We observed considerable genetic variation in sexual dimorphism among lines in both traits. The sexual dimorphic patterns remained relatively consistent across multiple trials, despite both traits being sensitive to environmental conditions. Additionally, we measured two sexually dimorphic adult morphological traits in six sampled lines and investigated correlations in the sexual dimorphism patterns with the two developmental traits. The abundance of genetic variation in sexual dimorphism for <em>D. melanogaster </em>developmental traits demonstrated in this study provides evidence for a high degree of evolvability of sex differences in pre-adult traits in natural populations.</p>

<p>Datasets and scripts encompasses landscape genetic analyses for giant root-rat populations, incorporating both mitochondrial and nuclear genome data. The study utilized resistance surface optimization approaches and partial Mantel tests to explore the impact of envrionmental features on the species. Findings and insights are detailed in the manuscript titled "Topographic barriers drive the pronounced genetic subdivision of a range-limited fossorial rodent".</p>

FIGURE 2 in Genista anglica s.l. (Fabaceae): genetic similarities between Iberian and Italian populations
FIGURE 2. Maximum clade credibility (MCC) tree resulting from BEAST phylogenetic analysis (20,000,000 generations) based on plastid (trnL-F) sequences data of Genista anglica group from Fernández Prieto et al. (2016) and new sequences. Support values are displayed on tree branches as posterior probability. Only the new samples codes are shown in the tree rapresentation. A TCS haplotype network, constructed with the same samples of ingroup of the phylogenetic tree is represented. Samples of each clade of the tree are represented with the same color in the haplotype network and the G. silana and G. brutia samples are indicated in the tree by circles and triangles with different lines patrons respectively, as in the corresponding circles of the haplotype network.
