|  | The correlation between
   App and heat shock protein 84-1 transcript is most impressive.  Since WebQTL now contains total of
   about 70,000 traits in the BXD strains, we could produce as many as to 70k x
   35k scatter plots of this type. Since all of the  correlations come for a common reference population,
   none  of the correlations are
   blantantly silly. However the great majority may be uninterpretable and a
   very large number may be meaningless given the signal-to-noise ratios of
   some measurements. With about 30 strains, correlations above 0.7 have a
   reasonably low false positive rate.
