What is the purpose of the hatchery and conditioning center

Basically it's a place where people are genetically engineered. The students view various machines and techniques used to promote the production and conditioning of embryos. The scientists take an ovary, remove and fertilize the eggs, force the eggs to bud up to ninety-six times, and subsequently grow the embryos in bottles. Predestinators then decide the future function of each embryo within the society, essentially assigning a future job to each human.
