Abstract Several methods exist for detecting genetic relatedness or identity by comparing DNA information. These generally require genotype calls, either single-nucleotide polymorphisms short tandem repeats, at the sites used comparison. For some samples, like those obtained from bone fragments single rootless hairs, there is often not enough present to generate calls that are accurate and complete these comparisons. Here, we describe IBDGem, a fast robust computational procedure genomic regions of identity-by-descent low-coverage shotgun sequence data against known query individual. At less than 1× genome coverage, IBDGem reliably detects segments can make high-confidence detections with as little 0.01× coverage.

These represent a biodiversity hotspot. While covering less than 1% Europe, they are home about one fourth all known European species. include high proportion endemisms, many which threatened.

The black abalone, Haliotis cracherodii, is a large, long-lived marine mollusc that inhabits rocky intertidal habitats along the coast of California and Mexico. In 1985, populations were impacted by bacterial disease known as withering syndrome (WS) wiped out >90% individuals, leading to closure all U.S. abalone fisheries since 1993. Current conservation strategies include restoring diminished translocating healthy individuals. However, population collapse on this scale may have dramatically lowered genetic diversity strengthened geographic differentiation, making translocation-based recovery contentious. Additionally, current prevalence WS remains unknown. To address these uncertainties, we sequenced analysed genomes 133 individuals from across their present range. We observed no spatial structure among with exception single chromosomal inversion increases in frequency latitude. Outside inversion, differentiation between sites minimal does not either distance or environmental dissimilarity. Genetic appears uniformly high Demographic inference indicate severe bottleneck beginning just 15 generations past, but decline short lived, present-day size far exceeding pre-bottleneck status quo. Finally, find agent equally sampled range, only 10% lack structure, uniform bacteria indicates translocation could be valid low-risk means restoration for species' recovery.

Highly repetitive TE sequences are also a major source of assembly gaps making it difficult to fully understand the impact these on host genomes.
