Evolutionary pressure analysis on dcNUMT gene clusters for mammals and birds
| Evolutionary pressure on dcNUMT gene clusters | No. of clusters mammals | No. of clusters in birds |
|---|---|---|
| Purifying selection (dN/dS < 1) | 247 | 24 |
| Neutral evolution (dN/dS = 1) | 726 | 73 |
| Positive selection (dN/dS > 1) | 23 | 1 |
-
Shown are the numbers of gene clusters that show clade-specific signatures of purifying selection, neutral evolution, and positive selection, respectively.
