X chromosome variants were associated to heritable fertility traits, in two bovine populations.
Fortes, Porto-Neto et al. 2020.
Background: Targeting phenotypes related to bull fertility, such as spe... morerm morphology and sperm DNA fragmentation can help identify mutations that limit reproduction capacity. Twenty-five fertility-related phenotypes were measured as indicators of bull fertility (1,099 Brahman bulls and 1,719 Tropical Composite bulls). Measurements included standard bull breeding soundness evaluation (e.g. sperm motility and morphology), scrotal circumference, and sperm DNA fragmentation and sperm protamine deficiency. These phenotypes were used in genome-wide association studies (GWAS) that aimed to estimate heritability and detect quantitative trait loci (QTL).
Results: Genomic analyses suggest that bull fertility traits have a heritable component, which makes selective breeding possible. The phenotype variation in sperm DNA fragmentation and sperm protamine deficiency traits have a heritable component (h2 ~ 0.05 – 0.22). These first estimates for heritability of sperm chromatin phenotypes require further studies, with larger datasets, to corroborate present results. Our GWAS identified eleven QTLs for bull fertility traits, based on five or more significant SNPs (P < 10-8). Six QTLs were identified in Brahman and five in Tropical Composite bulls. Most of the significant polymorphisms in both breeds and eight out of the eleven QTLs mapped to chromosome X. The autosomal QTLs were for sperm DNA fragmentation mapping to chromosome 11 (Brahman), for Inhibin mapping to chromosome 2 (Brahman), and for scrotal circumference mapping to chromosome 5 (Tropical Composites). The QTLs were breed specific, but for some traits, a closer inspection of GWAS reveals suggestive SNP associations (P < 10-7) in both breeds. For example, the Inhibin QTL observed in Braham might be relevant to Tropical Composites too, because we observed an association peak in that same region (many SNPs reaching P < 10-7). An example of breed specific results was the QTL for sperm midpiece morphological abnormalities, in the X chromosome (QTL peak at 4.92 Mb, P < 10-17). This QTL was supported by 487 significant polymorphisms (P < 10-8) in Brahman and yet it was absent in Tropical Composites. The reported GWAS add evidence to a mammalian specialization of X that evolved to harbor genes linked to spermatogenesis, as similarly observed in mice and humans. Some variants in X may affect more than one genetically correlated trait (r2 ~ 0.33 – 0.51), such as sperm morphology and sperm DNA fragmentation. Correlations and shared SNP associations support the hypothesis that these phenotypes have the same underlying cause: faulty spermatogenesis.
Conclusions: Genetic improvement for bull fertility is possible through selective breeding. Genomic selection for bull fertility might be more accurate if the X chromosome mutations that underlie the discovered QTL are included in the analyses. Polymorphisms associated with bull fertility accumulate in the X chromosome, as they do in humans and mice, thus, suggesting specialization of this chromosome.less

Reproduction and recruitment underlie the maintenance of biological communities. For most marine organisms the ocean environment provides the potential for widespread dispersal of organisms during var... moreious life cycle stages via currents, tides and wind.
Within the Kimberley region, key biological communities have a range of reproductive modes. Understanding patterns of larval connectivity is critical to managing the exposure of biological communities to disturbances in space and time.
KSN Project 1.1.3 employed genomic tools (microsatellite DNA markers and single nucleotide polymorphisms) and microchemistry to provide the first comprehensive measurements of the distances moved by marine organisms between Kimberley reefs, and how frequently organisms move between the Kimberley and other regions (e.g. offshore shoals, the Pilbara). The research also identified potential barriers to movement. Seven organisms (two
hard corals, two seagrasses, a mollusc, two fishes) were chosen as models for exploring connectivity in the Kimberley at both fine and broad scales.
This metadata record applies to three of the seven species investigated as part of project WAMSI 2 KSN 1.1.3. The data held is Raw SNP genotype. Metadata records associated with other species and lodged by AIMS, WA Museum, Curtin University, Department of Fisheries (WA) and Edith Cowan University can be accessed via Pawsey.

Data related to Naval-Sanchez et al. 2019 "Selection Signatures in heat-resistant cattle reveal missense mutations in damage response gene HELB".
Whole genome sequences from the 1000 Bull Gen... moreomes Project (Run6, Bos taurus, and Bos indicus) for breeds chosen as a reference for imputation were retrieved (Daetwyler et al. 2014; Hayes and Daetwyler 2018). This results in 440 whole-genome sequences across 18 cattle breeds.
Breeds were grouped in accordance to their phenotypes and reported genomic crosses as taurine (humpless), indicine (with hump), admixed or African sanga, the two latter being stabilized composite breeds (Rege J 1999; Hanotte et al. 2002; Rege J et al. 2007; Mwai et al. 2015; Felius, Marleen et al. 2016).
The dataset contains 186 European Taurine, 102 Asiatic indicine and 80 cross-bred genomes as well as a set of African samples composed of 12 taurine, 41 sanga and 19 indicine.
