High frequency of microsatellites in Drosophila pseudoobscura.
Using 30,000 bp of anonymous sequence data, we note that dinucleotide repeat arrays appear to be much more common in Drosophila pseudoobscura than in D. melanogaster or D. simulans. Repeat arrays bearing five or more units are situated on average once every 3000 bp in D. pseudoobscura, and repeat arrays bearing ten or more units are situated on average once every 7500 bp. We did not detect an association between microsatellite presence and GC-content of flanking regions.
