Hi! I have a question about genetic diversity seen as an ecological feature of the environment. Let me preface this by saying that although I have a BS in Biology, I now study something else. It remains something I am deeply interested in though! Here is my question: Is the level of genetic diversity in a population a parameter to which organisms adaptively react? For example, one could hypothesize that low diversity increases risks related to inbreeding, which would favor out-migration or outbreeding. Another hypothesis is that since a low genetic diversity leads a niche to be more saturated and increases the risk of competitive exclusion, it would also favor emigration. Yet another hypothesis is that in a low-diversity population, since the background similarity is high, the extra similarity added by close genealogical relations is comparatively low, which would make the payoff of kin altruism smaller.…
