    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.

    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.

    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.

    Gene flow mediates the role of sex chromosome meiotic drive during complex speciation

    Colin D Meiklejohn et al.
    Selfish genetic elements may either promote or prevent the evolution of reproductive barriers, depending on the extent of gene flow between species.

    Mycobacterium ulcerans dynamics in aquatic ecosystems are driven by a complex interplay of abiotic and biotic factors

    Andrés Garchitorena et al.
    Different transmission routes of Mycobacterium ulcerans to aquatic organisms may prevail depending on local physico-chemical conditions.

    A large gene family in fission yeast encodes spore killers that subvert Mendel’s law

    Wen Hu et al.
    Two members of a large fission yeast (Schizosaccharomyces pombe) gene family are shown to act as spore killers that enhance their own transmission into progenies by impeding the maturation of spores not inheriting them.

    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.

    The Natural History of Model Organisms: Advancing biology through a deeper understanding of zebrafish ecology and evolution

    David M Parichy
    The zebrafish is a premier model organism for biomedical research, with a rich array of tools and genomic resources, and combining these with a fuller appreciation of wild zebrafish ecology could greatly extend its utility in biological research.
