This avoids duplicating development work and allows each community to leverage upon its own tools and strengths.
While dosage balance may explain the initial selective retention of WGD duplicates, development of new functions or expression patterns is the norm in most well studied human gene families.
Customers can also create duplicate environments for development and test purposes.
Finally, based on the spatial expression of Zebra fish duplicate proteins during development, we found that protein pairs containing asymmetrically evolving domains had a greater divergence in gene expression as compared to the duplicate proteins that did not exhibit asymmetric evolution.
The overlap is inefficient: it duplicates research and development, reduces economies of scale and destroys pricing power.Companies often stay in markets where they cannot compete.
Although nine of the ten opsins in this study were recovered from cDNA and thus expressed to some level, there can be extreme variation in opsin expression levels, both between duplicates and during development, therefore it is possible that at any given time only a portion of the repertoire is functionally significant [46], [47].
Two genes, WR1 and WR2 showing duplicate interaction governs the development of aleurone layer colour (wine red / dark wine red/light) with NaOH and KOH in rice plants.
There also are significant differences in spatial expression patterns for the duplicated CYP17A genes during development, and during the spawning cycle in other fish [ 32].
Interestingly, both types of relocation patterns (i.e., [X → A] and [A i → A j]), contribute with the same intensity to the differences in expression between parental and duplicated genes during sperm development (supplementary fig. 3, Supplementary Material online).
