The X chromosome is a key player in germ cell development, as has been highlighted for
males in previous studies revealing that the mammalian X chromosome is enriched in genes …

The mammalian Y chromosome is critical for male sex determination and spermatogenesis.
However, linking each Y gene to specific aspects of male reproduction has been …

Current phylogenomic approaches implicitly assume that the predominant phylogenetic
signal within a genome reflects the true evolutionary history of organisms, without assessing …

The chicken continues to hold its position as a leading model organism within many areas of
research, as well as being a major source of protein for human consumption. The First …

Genes involved in spermatogenesis tend to evolve rapidly, but we lack a clear
understanding of how protein sequences and patterns of gene expression evolve across this …

The mammalian sex chromosomes harbor an abundance of newly acquired ampliconic
genes, although their functions require elucidation [1–9]. Here, we demonstrate that the X …

Widespread loss of genes on the Y is considered a hallmark of sex chromosome
differentiation. Here we show that the initial stages of Y evolution are driven by massive …

Whole tissue RNASeq is the standard approach for studying gene expression divergence in
evolutionary biology and provides a snapshot of the comprehensive transcriptome for a …

Sex chromosomes are havens for intragenomic conflicts. The absence of recombination
between sex chromosomes creates the opportunity for the evolution of segregation …

The mouse sex chromosomes exhibit an extraordinary level of copy number amplification of
postmeiotically expressed genes [1, 2], driven by an" arms race"(genomic conflict) between …
