A genetic screen is an experimental technique used to identify and select for individuals who possess a phenotype of interest in a mutagenized population. Hence a genetic screen is a type of phenotypic screen. Genetic screens can provide important information on gene function as well as the molecular events that underlie a biological process or pathway. While genome projects have identified an extensive inventory of genes in many different organisms, genetic screens can provide valuable insight as to how those genes function.

Famous quotes containing the words genetic and/or screen:
“Nature, we are starting to realize, is every bit as important as nurture. Genetic influences, brain chemistry, and neurological development contribute strongly to who we are as children and what we become as adults. For example, tendencies to excessive worrying or timidity, leadership qualities, risk taking, obedience to authority, all appear to have a constitutional aspect.”
—Stanley Turecki (20th century)
“She was custom built for the pictures—teeny tiny, one inch less than five foot, and a perfectly enormous head. Her face went right from one side of the screen to the other. Gloria Swanson was like that, as well. Joan Crawford, too. You need the big face, for the closeups.”
—Angela Carter (1940–1992)
