Query: Genetic recombination as a Generalised Gradient Flow   It is well known that the classical recombination equation for two parent
individuals is equivalent to the law of mass action of a strongly reversible
chemical reaction network, and can thus be reformulated as a generalised
gradient system. Here, this is generalised to the case of an arbitrary number
of parents. Furthermore, the gradient structure of the backward-time
partitioning process is investigated.
