Gene duplication is an important source of evolutionary innovation. To explore the relative
impact of gene duplication during the diversification of major insect model system lineages …

ABSTRACT Y chromosomes have male-limited inheritance, which favors the fixation of
alleles that affect spermatogenesis, courtship, and other male-specific traits. Y-linked male …

Gene duplication is increasingly recognized as an important mechanism for the origination
of new genes, as revealed by comparative genomic analysis. However, the ways in which …

The housefly Musca domestica is a commonly used model system to test theories on sex
determination and sex chromosome evolution. These studies are however impeded by our …

During the process of adaptation, phenotypic variation present within a population provides
the substrate on which selection may act. However, in light of epigenetic processes, the …

Results Hundreds of young Pack-TIRs were identified in animal reference genomes and
population resequencing data of D. melanogaster. To generate a comprehensive view of …

Contrary to dogma, evolutionarily young and dynamic genes can encode essential
functions. We find that evolutionarily dynamic ZAD-ZNF genes, which encode the most …

Retrogenes are a group of functional genes produced by gene retroduplication events
during evolution. It has been observed that many retrogenes have formed since the …

The set of genes in the genome of a species is the result of a dynamic net balance between
gain and loss events that happen over evolutionary time. The origination and divergence of …

The centromere is a specialized chromatin region that is critical for faithful chromosome
segregation. Centromere function is conferred epigenetically, by the presence of a histone …
