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.

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

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.

The TRAIP ubiquitin ligase is required during mitosis to disassemble the replisome at sites of incomplete DNA replication, and activate the mitotic DNA repair pathway, thus preserving genome integrity.

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

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

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.

Members of a single gene family determine the genomic basis of multiple coexisting meiotic drive elements in natural populations of Podospora.

Polo kinase recruitment by the protein Spd-2 to the pericentriolar scaffold is a key element of the positive feedback loop which drives the expansion of the mitotic centrosomes in flies.
