We observed (fig. 4 B ) that duplicates with testis-specific expression are evolving 2.2 times faster than their parental genes ([d N/d S] of 0.082 and 0.037, respectively; P = 5 × 10−5; Wilcoxon rank sum test, after applying Bonferroni's correction).

It has been stated above that duplicated genes with full redundancy can be expected to reduce to a single copy over time through the stochastic accumulation of mutations that harm one of the genes.
With that duplicate text selected, go to Filters>Blurs and click Motion Blur, horizontal.
Finally, we asked whether noncoding sequences associated with genes that duplicated in the hominin lineage show stronger evidence of divergence than noncoding sequences nearby nonduplicated genes.
In the case of a SNP site that is duplicated with (haploid) copy number two, there are theoretically five possible haploid genotypes for that SNP: AA, AB, BB, A, and B, where A and B are the two base residues for the SNP site.
Multiple mappings show that flanking sequences map to regions of the D. melanogaster that are duplicated with respect to the query species.
The distribution of duplication spans for partial duplicates (n = 26 pairs) was similar to that of complete duplicates, with a range of 320 – 10,091 bp but with a lower median value of 1814 bp.
Finally, our analyses of evolutionary rates reveal that mitochondrial duplicates with testis-specific expression evolve faster than parental genes but are still under strong purifying selection ([d N/d S] = 0.082; 95% confidence interval [CI]: 0.0640 – 0.0640).
We observed that gene duplicates with asymmetric rate evolution have significantly higher Asy values between duplicated genes in comparison to those with symmetric rate evolution (Pearson's correlation test, r = 0.2476, P = 6.929 × 10−6; fig. 6 a ), suggesting that asymmetric rate evolution is often associated with asymmetric expression divergence.
To test the hypothesis that duplicated genes with imprinting frequently show asymmetric sequence rate evolution compared with their paralogs, we used 46 alpha WGD gene pairs where one gene in the pair shows imprinting (Hsieh et al. 2011; Wolff et al. 2011).
Our finding is that duplicate pairs with different biological processes differ significantly in D HM-P and D HM-O (P < 10-13 for D HM-P , P < 10-15 for D HM-O ; Table 1).

Since I tried Ludwig back in 2017, I have been constantly using it in both editing and translation. Ever since, I suggest it to my translators at ProSciEditing.
