Progenation
From Tardis Wiki, the free Doctor Who reference
Progenation is a method of artificial reproduction from a single organism wherein one parent is biological mother and father. It involved taking a sample of diploid cells, splitting them into haploids, then recombining them in a different arrangement and then grown into an offspring. During the Human-Hath War on the planet Messaline, both the Human and Hath factions used progenation machines to generate their armies. The specific method used in that conflict was able to created and grow a new offspring in a matter of moments.
