"Correction" was the name given to the phase that had begun after the first round of Gestations, when Eve Moira had fixed errors that had led to several nonviable infants. In a sense, Correction went on continuously all through the first round of Gestations and began to taper off as the daughters of the Eves began to produce second-generation children. It faded into a next stage, Stabilization, which lasted through the following ten generations or so as Y chromosomes were patched up, lingering genetic mistakes were fixed, and members of different Strains began to interbreed to produce hybrids within their own racial groups. During this time the lessons of the black-footed ferret were put to use as various techniques were employed to increase heterozygosity.
