Abstract: The present invention relates to a method for reducing the competitive fitness of an organism hemizygous for a transgenic locus compared to the organism homozygous for the transgenic locus comprising the steps of: (a) reducing the expression of a haploinsufficient gene in the organism, wherein said reduction is conveyed by a transgenic locus in the organism; and (b) rescuing the reduced expression in the organism, wherein said rescue is conveyed by the same transgenic locus in the organism, yielding an organism which is less competitively fit if hemizygous for the transgenic locus than if homozygous for the transgenic locus.

Abstract: A retainer apparatus and method is disclosed for retaining a form mold in a selected position that includes a beam having a longitudinal axis and a retaining member slidably engaged to the beam allowing for free movement along the longitudinal axis when said retaining member is in a free state. The retaining member has a lengthwise axis substantially perpendicular to the longitudinal axis in the free state, with the retaining member also including a leg substantially parallel to the lengthwise axis, the leg extending from the slidable engagement and terminating in a form mold interface portion. The retaining member also including a head portion extending from the slidable engagement being substantially oppositely disposed from the leg. The retainer apparatus is place into the locked state by applying a force to the leg to substantially lock the slidable engagement and retaining the form mold.
