Table 2

Gene density. Autosomes are divided into the genetically defined compartments of the left arm (L), the central cluster region (C), and the right arm (R). The percentage of genes with EST and database matches was determined only from manually inspected genes. Database matches to nonnematode proteins were determined with WUBLASTP (P ≤ 0.001). Parentheses denote the number of low-scoring predictions thought to be pseudogenes.
