Table 3 Number of the conserved orthologous markers between grass carp and four model fish species

Type^a	Zebrafish	Tetraodon	Fugu	Medaka
1	126	3	3	2
2	12	8	2	2
3	13	12	15	6
4	13	13	13	13
Total (%)^b	164 (59.2%)	36 (13.0%)	33 (11.9%)	28 (10.1%)

'^a', shows the conservation of orthologs, e.g., type 1 indicates unique orthologs identified for each model species, type 2 shows orthologs identified only in two model species (the given model species and another model species), type 3 shows orthologs identified in three model species (the given model species and other two model species), etc; ^'b', ratio of all orthologous markers to the total informative markers used for similarity searches.
