The number of members was calculated using the CLOBB clustering algorithm. Genes are shown by the EST number that is representative of the cluster members. AA0383 is the same cluster member of OC2756, which is highly expressed in the ovary, as shown in Table 4. "n.h." denotes no homology in BLAST searches (see Gene annotation in Methods).
