Each immigrating citizen has her DNA significantly upgraded soon after signing in, while respecting her original characteristics (improvement, not transmutation).

On the other hand, Lawrence himself doesn't have a DNA of his own, instead drawing on a massive catalogue of replicated genetic templates (multiplied exponentially via gene-splicing and engineering), and automatically shifting the seed's template according to his current partner to optimally complete her own DNA when conceiving.

So the continuity of the bloodline entirely relies on the maternal side, and from a purely genetic perspective, every child is born from a different father.
