recombinationia
Recombinationia is a hypothetical genetic mechanism proposed in theoretical discussions of genome evolution. It denotes a class of recombination events in which modular DNA segments from disparate genomic loci are reorganized into mosaic arrangements, yielding novel gene cassettes while preserving essential regulatory relationships. The concept is intended as a thought experiment to explore how genomes might adapt rapidly under selective pressures when standard homologous recombination is limited.
Etymology and scope: The term combines recombination with the -ia suffix used for conceptual phenomena. It is
Proposed mechanisms: In the recombinationia framework, two processes are invoked: modular shuffling, where non-homologous yet motif-compatible
Implications and critique: If feasible, recombinationia could accelerate functional diversification without large-scale duplications, potentially aiding adaptation
