Abstract:
Sexual reproduction is modeled an investigated in the
formal framework of John von Neumann's theory
of self-reproducing cellular automata.
It is argued that the transition from asexual to
sexual reproduction necessitates a change in number and
structure of the genetic tapes involved.
It is shown that the  recombination of the parent's
characteristics closely conforms to nature. Similarities
with biological systems are discussed and e.g. a concrete
hypothsis on the X-Y mechanism for the physiology
of sexual processes is presented.
