For this to occur, there must be forces that systematically diminish this variation (that is, that cause 'negative linkage disequilibrium'), such as genetic drift or negative epistasis.

Background: Night shift work has been associated with adverse health outcomes. Whether night shift work is associated with cholelithiasis remains uncertain, and the roles of genetic risk and lifestyle ...

Could this genetic shift lead to stronger, faster, or even more intelligent predators? Or will it spell disaster for already endangered species? In this video, we break down what this mutation is ...

Hybrid immunity, through vaccines and exposure to the virus, is likely to protect people but they still need to follow Covid appropriate behaviour, says the health expert ...

Genetic markers are DNA sequences with known physical locations on chromosomes. They are points of variation that can be used to identify individuals or species, or may be used to associate an ...

Different work schedules can be established for different employees, such as a day shift, evening shift and night shift. Depending on the company's business needs, employers may require employees ...

The Switch 1 Joy Cons have been plagued with drift problems for years. Other changes to the Joy Con design may prevent drift, but only time will tell. Stick drift was one of the most notorious and ...

Researchers believe this change coincides with the arrival of pottery and farming techniques, marking a major cultural and genetic shift in the region. Chibchan ancestry spread south and remained ...

Researchers suggest that this genetic shift could have been crucial in the eventual emergence of Homo sapiens, as well as the later differentiation of Neanderthals and Denisovans. These changes ...

An international research team from the University of Tübingen, the Senckenberg Center for Human Evolution and Palaeoenvironment and the Universidad Nacional de Colombia have now found genetic ...
