Second, in some excision events, the element is excised only partially, which may result either in the same phenotype or in one distinct from the original insertion. Examples are lines M22 and M25, which show reduced TBH signal (Fig. 5C).
Balancer chromosomes were first used in the fruit fly by Hermann Muller, who pioneered the use of radiation for organismal mutagenesis. In the modern usage of balancer chromosomes, random mutations are first induced by exposing living organisms with otherwise normal chromosomes to substances which cause DNA damage; in flies and nematodes, this usually occurs by feeding larvae ethyl methanesulfonate (EMS).
