Table 2.

Summary of identified teleost OR genes. OR sequences identified in the present study are listed in this table.

	Zebrafish	Fugu	Tetraodon
Intact genes a	143 (7)	44 (3)	42 (6)
Partial genes b	7	9	4
Pseudogenes c	10	4	11
Total	160	57	57

^a A gene is operationally defined as "intact" if it possesses a full-length OR protein coding sequence with no more than one disruption. For each species, the number of genes with a single disruption is listed in parentheses; the remainder contain no disruptions.

^b A sequence encoding ≤ 275 contiguous amino acids, missing specific features characteristic of ORs (see the text for details), or missing start or stop codons is classified as a partial gene.

^c A sequence is defined as a pseudogene if it is a partial gene with one or more disruption or a full-length gene with 2 or more disruptions.
