USAGE
The correct spelling is heterogeneous but a fairly common misspelling is heterogenous. The reason for the error probably relates to the pronunciation, which, in rapid speech, often misses out the extra e. In the British National Corpus, the misspelling occurs in 5 per cent of citations for the word.
