11. A method of identifying a mutation in a gene of interest of an organism, the method comprising the steps of
a) providing a mixture of pooled DNA samples, each said DNA sample of said pool being from a mutated organism; -
b) providing a nucleic acid probe unique to a gene of interest; c) testing said mixture for a mutation in said gene of interest by hybridizing said probe to said mixture without the prior observation of a phenotypic alteration in each said mutated organism. - View Dependent Claims (12, 13, 26, 51, 53)

15. A method of identifying a mutation in two or more genes of interest in an organism, the method comprising the steps of
a) providing a DNA sample from a given tissue of a mutated non-transgenic organism, wherein said mutated organism contains about 1 mutation in 1000 genes, b) providing plural nucleic acid probes, each said probe being unique to a given gene of interest, c) testing said DNA sample for a mutation in a said gene of interest without the prior observation of a phenotypic alteration in said mutated organism.

29. In a method of inducing and identifying a mutation in a gene of interest in a non-transgenic organism, wherein the organism is exposed to a mutagen so as to induce a mutation in the genome of the organism, and the organism is then mated to produce an offspring containing the gene of interest, the improvement comprising the step of
testing the gene of interest for a mutation without the prior selection of a phenotypic characteristic in the offspring.
