Surprisingly, in the long fluorescent domains, NvFP-7R was detected in complementary expression domains in the two apposed endodermal cell layers comprising each mesentery (Figure 4C and 4F–F').
Other models have been proposed including sub-functionalization [ 59, 60], where both duplicates accumulate mutations resulting in complementary expression, leaving each copy with its own sub-function.

Lister, J. A., Close, J. & Raible, D. W. Duplicate mitf genes in zebrafish: Complementary expression and conservation of melanogenic potential.
As shown in figure 2, there is no complementary expression in mitochondrial families that do not contain genes with testis-biased expression.
The results showed that ZmNAS genes were merely accumulated in reproductive organs and exhibited complementary expression patterns in vegetative organs.
We conclude that the nuclearly encoded mitochondrial duplicates that have complementary expression in adult tissues also exhibit complementary expression in different spermatogenesis stages, showing important differences between meiosis and postmeiosis, in which the new genes are highly expressed, but parental genes are expressed at low levels.
They integrated genotypic and expression data for individuals in a segregating population with complementary expression data of strains mutated in a variety of regulatory proteins, in order to identify regulatory-linkage modules.
The greatest overlap was between petal and leaf versus leaf and seed, with 74 paralogous gene pairs showing complementary expression in both of these comparisons.
Another difference is that we did not analyze upregulation and downregulation of expression level (i.e., quantitative complementary expression) in this study instead focusing on reciprocal expression patterns (i.e., qualitative complementary expression).
This example illustrates how spatial subfunctionalization (complementary expression in rhombomeres 4 and 5) is directly reflected by cis-regulatory subfunctionalization. Subfunctionalization may also be observed in the temporal expression domain.
Second, parent-retrogene pairs moving out of the X chromosome have higher complementary expression in meiosis, that is parental gene down-regulation and retrogene up-regulation, than those pairs moving between autosomes [ 25].

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.
