Кислород, разумеется, наверняка замешан, но почему неправда? http://www.ncbi.nlm.nih.gov/pubmed/12187379 "In summary, we have shown that one physiological trait, namely, oxygen metabolism, is linked to the genomic composition of prokaryotes, leading to a remarkable increment in GC% among aerobic species. Since this increment is contrary to the expected mutation pattern, it follows that a high genomic GC% is selectively favored in aerobiosis. Indeed, natural selection could be responsible for the skewed distribution of GC% among aerobic organisms, while the absence of the selective factor (O2) could account for the normal distribution centered at a nonbiased GC% among anaerobic organisms."
***Если отбор действует непосредственно на геном, то геном и есть фенотип.*** Т.е. понятие фенотипа нужно расширить еще дальше, и практически включить в него генотип :)
