  We study the continuous-time evolution of the recombination equation of
population genetics. This evolution is given by a differential equation that
acts on a product probability space, and its solution can be described by a
Markov chain on a set of partitions that converges to the finest partition. We
study an explicit form of the law of this process by using a family of trees.
We also describe the geometric decay rate to the finest partition and the
quasi-stationary behavior of the Markov chain when conditioned on the event
that the chain does not hit the limit.
