title: Fisher's reticulate mating system for immigration into an improved stock.
abstract: A reticulate mating system is described which was designed by the late R.A. Fisher to permit the introduction of new genetic variability into an improved stock by immigration. Analysis of part of a long-term experiment to alter the degree of dominance of the mutant Sd in mice using the system demonstrates a rapid response. Its applicability to stocks of animals of economic value is considered.
