Traits that help one sex but hurt the other are not sufficient for maintaining genetic variation. From GLP-1 pioneers to researchers who uncovered the genetic roots of narcolepsy, scientists reveal ...

A new model, vetted by experiments on lung cancer cells, may help to explain how cancer and other diseases accumulate drug-resistance mutations that can compromise the effectiveness of treatments.

Dan MacArthur has a post up, Climate genes: positive or balancing selection?, where he questions the interpretation of data from a recent paper, Adaptations to Climate in Candidate Genes for Common ...

Balancing selection is a fundamental evolutionary force that maintains multiple alleles at a locus within a population over extended periods. Unlike directional selection, which drives alleles to ...
