Which is the ultimate source of RECOMBINATION in the nearest environment of the genome,both haploid & diploid?

Question

Recombination is an exchange of genetic material between two homologous chromosomes, that I know. But I am not sure about the ultimate factors for it available in the immediate environment of the haploid or diploid genomes i.e., chromosomes towards recombination of various genes between the individual chromosomes, yielding to a variety of combinations for individuals, especially in the species of human beings. Please, check it out for me... I am doing a project on it.

Answer 1

The ultimate source of recombination would have to be the genetic material itself.

ADDED
As far as I know, this is assumed to be a random process. But I never like the sound of that because what is assumed to be "random" often turns out to have an underlying algorithm or process to it.

You could postulate that microenvironmental factors such as pH, or unavailability of energy resources or enzymes, or uncharacteristic "stickiness" of the chromosomes such that material was inaccurately transferred could affect the process and therefore the outcome, but you'd need to do a scientific literature search for these or other possibilities and I don't have access to that at the moment.
