๐ŸŽ‰ PAPER OUT ! Happy to see another chapter of my PhD out in #MBE ! The African pygmy mouse flips the script on sex determination. Its multiple sex and neo-sex chromosomes ๐Ÿคฏ shape brain transcriptomes and drive sexual polymorphism, reflecting new evolutionary trajectories for sex-linked regions.

Heitzmann et al. compared brain transcriptomes of four sexual genotypes of the African pygmy mouse, showing how sex and neo-sex chromosomes impacted transcriptomes to reflect their transmission mode, evolutionary trajectories, and genomic conflicts.
