这种自发突变发生在杰克逊实验室。这种突变导致的表型类似于原始致死斑点突变，且位于染色体2的同一区域，但由于它是显性的，所以没有进行补救测试。 (Source: This spontaneous mutation originated at The Jackson Laboratory. The mutation results in a phenotype akin to that of the original lethal spotting mutation, and is located on chromosome 2; however, due to its dominance, no complementation test was conducted.)
