Suppose we want to maintain a large number of homozygous lethal chromosomes, exposed to chemical mutagens, for a mutation screening experiment in a small orb web building spider species. One of these lines has a dominant mutant named Disordered (D) that results in “messy” web building.
How can we modify the Disordered line to use as a genetic tool to maintain the mutant chromosome stocks?
