genetic screens

Genetic screens are experiments used by scientists to discover which genes in an organism influence specific traits or functions. By systematically altering or observing genes (often in model organisms like fruit flies or yeast), researchers can identify which genes are responsible for certain behaviors, diseases, or biological processes. This helps in understanding how genes interact and can lead to advancements in areas like medicine, agriculture, and biology. In essence, genetic screens allow scientists to "screen" through a vast library of genes to find the ones that matter for a particular question.
