And, in addition to duplication rates, gene duplicability is also determined by survival rates of duplicate genes.
The higher duplicability of tandem duplicates may also leave more recent and less divergent gene pairs.
The duplicability of tandem duplicates is also higher than that of retrogenes.
Because the number of interactions often changes greatly after duplications [ 19, 41], the observed degree-duplicability correlation may also be interpreted as that degrees decrease after duplication by divergence rather than that the duplicability itself is dependent on a degree.
Prachumwat and Li [34] reported a negative correlation between the degree of proteins and their duplicability.
Dosage sensitivity is an important evolutionary force which impacts on gene dispensability and duplicability.
In Drosophila, developmental constraint, for instance, does appear to reduce gene duplicability, but the effect is moderate [10].
A critical issue is gene duplicability.
Thus, higher gene duplicability is accompanied by higher sequence diversifiability.
High duplicability is confined to select groups of genes.
We hypothesized positive correlations between gene duplicability and diversifiability.
