Despite polymorphic duplicate genes' importance for the early stages of duplicate gene
evolution, they are less studied than old gene duplicates. Two essential questions thus …

Sex differences in the fitness effects of genetic variants can influence the rate of adaptation
and the maintenance of genetic variation. For example,“sexually antagonistic”(SA) variants …

Comparative genomics has enabled the identification of genes that potentially evolved de
novo from non-coding sequences. Many such genes are expressed in male reproductive …

Tandem duplication, one of the major types of duplication, provides the raw material for the
evolution of divergent functions. In this study, we identified 1 pair of tandem duplicate genes …

The newly evolved gene Heterochromatin Protein 6 (HP6), which has been previously
classified as essential, challenged the dogma that functions required for viability are only …

It is a conventionally held dogma that the genetic basis underlying development is
conserved in a long evolutionary time scale. Ample experiments based on mutational …

The acquisition of novel sexually dimorphic traits poses an evolutionary puzzle: How do new
traits arise and become sex-limited? Recently acquired color vision, sexually dimorphic in …

Several functional classes of short noncoding RNAs are involved in manifold regulatory
processes in eukaryotes, including, among the best characterized, miRNAs. One of the most …

Despite long being considered as “junk”, transposable elements (TEs) are now accepted as
catalysts of evolution. One example is Mutator-like elements (MULEs, one type of terminal …

Abstract The Transforming Growth Factor-β mimic (TGM) multigene family was recently
discovered in the murine intestinal parasite Heligmosomoides polygyrus. This family was …
