I'm looking for alternate ways to explain effective populations size, in more conceptual terms. These need not be perfectly accurate "definitions" but should at least be generally accurate in non-edge cases.
For example, if I have a population with a supposed effective population size of 1000, what (if anything) can I conclude about the amount of genetic diversity present within a single individual sampled at random from the real (census) population?
Like, would it be overly simplistic to say that the sampled individual could be expected to contain ~1/1000 of the population's standing variation? Or to say that a given (observed) nucleotide state has a 0.001 probability of being fixed?
Again, I'm looking for anything that is not the standard way to explaining Ne to somehow get a student's head partly into the game without being wholly misleading. Thank you
