Comparison of the Number of Sea Urchin and Ciona Orthologs Assigned in the CD/CDY Orthologous Groups
| CD/CDY group size | Number of CD/CDY groups for urchin/ciona | Percentage of CD/CDY groups for urchin/Ciona |
|---|---|---|
| 1 | 1037/1808 | 67.6/61.4 |
| 2 | 284/550 | 18.5/18.7 |
| 3 | 107/218 | 6.98/7.41 |
| 4 | 38/118 | 2.48/4.01 |
| 5 | 23/53 | 1.50/1.80 |
| 6 | 12/45 | 0.78/1.53 |
| 7 | 10/31 | 0.65/1.05 |
| 8 | 4/26 | 0.26/0.88 |
| 9 | 2/22 | 0.13/0.75 |
| 10 | 1/20 | 0.07/0.68 |
| >10 | 13/50 | 0.84/0.42 |
A total of 2782/5198 sea urchin/Ciona genes were assigned in 1532/2941 CD/CDY groups, respectively. CD/CDY groups containing more than 10 orthologs are grouped. The average copy rates per CD/CDY cluster are calculated from these numbers as 1.8 for sea urchin and 1.76 for Ciona.
