    Genome rearrangements and pervasive meiotic drive cause hybrid infertility in fission yeast

    Sarah E Zanders et al.
    Rapid acquisition of chromosome rearrangements, together with independently acting transmission distorter alleles on each chromosome, drive near complete sterility in fission yeast hybrids.

    Loss of heterozygosity results in rapid but variable genome homogenization across yeast genetic backgrounds

    Abhishek Dutta et al.
    Loss of heterozygosity (LOH) mediated diversification of the diploid S. cerevisiae hybrid genomes during asexual propagation are vast and exceptionally varied depending on the genetic background.

    wtf genes are prolific dual poison-antidote meiotic drivers

    Nicole L Nuckolls et al.
    Selfish wtf meiotic drive genes use overlapping transcripts to encode both a trans-acting poison to kill gametes that do not inherit the gene and a gamete-autonomous antidote to specifically rescue the gametes that do.

    CatSperζ regulates the structural continuity of sperm Ca2+ signaling domains and is required for normal fertility

    Jean-Ju Chung et al.
    A new component, CatSper zeta, is required for continuous alignment of the calcium channel along the sperm's tail and is crucial for normal sperm swimming behavior and fertility.

    Atypical meiosis can be adaptive in outcrossed Schizosaccharomyces pombe due to wtf meiotic drivers

    María Angélica Bravo Núñez et al.
    The wtf meiotic drivers change the fitness landscape of meiosis in outcrossed Schizosaccharomyces pombe demonstrating that genetic parasites can favor the evolution of variants that disrupt meiotic fidelity.

    Meiotic drive of female-inherited supernumerary chromosomes in a pathogenic fungus

    Michael Habig et al.
    Female-inherited supernumerary chromosomes that lack a male-inherited homolog are transmitted to all meiotic products instead of the expected half, which indicates an additional amplification of unpaired chromosomes during meiosis.

    Heredity: The gene family that cheats Mendel

    J Dylan Shropshire, Antonis Rokas
    Some alleles of the wtf gene family can increase their chances of spreading by using poisons to kill other alleles, and antidotes to save themselves.

    COMP-1 promotes competitive advantage of nematode sperm

    Jody M Hansen et al.
    Nematode sperm respond to competitive environments by modulating cellular pathways involved in migration and storage to ensure their access to oocytes.

    Navigating the garden of forking paths for data exclusions in fear conditioning research

    Tina B Lonsdorf et al.
    Exclusion of participants in tasks with a learning element can introduce substantial bias and needs to be carefully considered and transparently reported and justified.

    TRPV4 is the temperature-sensitive ion channel of human sperm

    Nadine Mundt et al.
    The molecular identity of the temperature-sensitive ion channel of human sperm that ensures depolarization is TRPV4.
