If humans needed to repopulate after an extinction event from a relatively small number or if we were to send a multi-generational ship to a distant place in our galaxy, would it be beneficial for the health of the future generations to engineer/plan the offspring instead of sticking to the traditional family-model of two random people falling in love and producing kids?
