But there are many more factors...some of which we are only just now gaining glimpses of. For example, recently an article appeared in Science describing yet another previously unknown mechanism by which nature efficiently filters mutations and preserves genetic integrity by passing messenger RNA during mitosis.
A bit more detail of what research you are thinking of would be helpful here.
If you mean the
Hothead research (
Lolle, et al., 2005), which was actually published in Nature although there was a news article about it in Science (
Pennisi, 2005), then you are perhaps tending towards presenting something as an observed mechanism which is at best a tentative hypothesis. The mechanism behind the revertant phenotype of the
Hothead revertants is still a mystery as far as I know. The mRNA hypothesis was just that, a hypothesis. the research did not demonstrate any wild-type
Hothead mRNA was actually present in the gametes to act as a template. The only actual observation was that there were revertants both phenotypically and genetically, the basis of the reversion is unknown, or at least unpublished.
Of course you might not be thinking of the
Hothead research at all, in which case I am just rambling on to no end. If you are talking about the
Hothead research then we know even less about the mechanisms of the reversion, if it is a real phenomenon and not an artifact as some claim, than you think.
