Recently sequenced Daphnia pulex genome has some surprises:
- Daphnia pulex has a tiny genome containing only 200 million base pairs (compared to 3 billion in humans), yet has 31,000 genes within it (cf. humans have only 23,000 genes).
- Roughly a third of Daphnia pulex genes are unique to this species and many of these genes are duplicated (twice the frequency of C. elegans)
