Distribution of EST coverage for OR genes. Bars show observed distributions for ESTs (spliced and non-spliced) coverage in non- olfactory tissues. The ESTs utilized for the distributions calculation were from normal tissues, non-subtracted and non-normalized libraries. Distributions for A. human intact ORs, B. human 7E subfamily ORs, C. human pseudogenes (excluding 7E subfamily members), D. mouse ORs (intact and pseudogenes). Solid lines are computed Poisson distributions based on the average value of ESTs per OR gene. The fit to the expected Poisson distributions was tested using the Kolmogorov-Smirnov test. The resulting p-values are: 0.998 for A, 0.003 for B, 0.401 for C and 0.591 for D.
