An Ode to P.G.D. [limericks]

Through preimplantation genetic diagnosis
can we screen out the embryos prone to nerosis?
    if cancer doesn't loom
    in your embryonic bloom
perhaps we'll select you for further mitosis

In vitro fertilization allows the fine-tuning
of whether your larynx sustains suasive crooning
    cannot poetry potentially
    be selected for? eventually
philharmonics boast superlative genetics-wraught bassooning

With preimplantation genetic diagnostics
we select for the CEO and weed out the beatniks
    biotech bodes a future
    cafeteria of Nature
permitting us to sire keen inventors of Sputniks

In vitro fertilization permits the selection
of the predispositions for human perfection
    why live so haphazard
    as the fruitflies and lizards?
genitalia and gizzards we improve with reflection

Via preimplantation genetic diagnostics
we aim to distinguish the dumbos from gnostics
    pre-prenatal IQ testing
    can be swiftly arresting
those embryos not favored for crosswords & acrostics
