Comments P.6 right column 2nd paragraph: "Dinoflagellate gene contents and their implications in genome evolution: While all the available information point to a reasonable accuracy, or at least no overestimation, the model-predicted gene numbers for dinoflagellates (38,188–87,688 or about 1-3 fold as many as that in a human genome) are exceedingly high for these unicellular and therefore relatively “simple” organisms. However, these gene number estimates may not really represent an extraordinarily high functional diversity of the encoded proteome. A survey of literature reveals that previously examined dinoflagellate genes occur in 30–5,000 copies per genome (Table 2), indicating that high gene copy number is a widespread phenomenon in dinoflagellate genomes." P.7 right column top paragraph: "Tandem-repeated genes, like those that have been studied in dinoflagellates (Table 2), are more likely to have resulted from successive gene duplications through unequal cross-over of chromosomes [primary source 16]."
