This set of five PowerPoint slides featuring questions for problem-based discussion (i.e., open-ended questions that engage students with each other and with course material) can be easily incorporated into lectures on genetic drift. (berkeley.edu)

Genetic variants of the LRBA and the MAT2B genes might be significant genetic markers of drug hypersensitivity reactions. (confex.com)

The closest relatives of the common raven are the brown-necked raven ( C. ruficollis ), the pied crow ( C. albus ) of Africa, and the Chihuahuan raven ( C. cryptoleucus ) of the North American Southwest. (wikipedia.org)

Understanding the effect of inherent common genetic variation on regulation of tau gene expression. (ucl.ac.uk)

It's also instructive that one single gene is not solely responsible for high triglyceride levels but rather a mosaic of both common and rare variations in several genes. (scienceblog.com)

This metric only looks at common gene variants. (bigthink.com)

Overall, we provide genetic insights into MPB: a phenotype of interest in its own right, with value as a model sex-limited, complex trait. (nature.com)
Our findings suggest that S. pneumoniae pathogenicity is complex and multifactorial, and we provide genetic evidence for precise targeted interventions. (cdc.gov)

In fact, ASD is highly genetically heterogeneous due to multiple familial inheritance patterns and the occurrence of a large number of de novo variations. (nature.com)
