Genetic screen  From Wikipedia, the free encyclopedia
  (Redirected from Positional cloning) Jump to: navigation,
search  A genetic screen is an experimental technique used to
identify and select for individuals who possess a phenotype of
interest in a mutagenized population.[1] 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.[2][3][4][5][6]
Basic Screening[edit]  Forward genetics (or a forward genetic
screen) is an approach used to identify genes (or set of genes)
responsible for a particular phenotype of an organism. Reverse
genetics (or a reverse genetic screen), on the other hand,
analyzes the phenotype of an organism following the disruption
of a known gene. In short, forward genet
