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.
Prdm9-generated meiotic asynapsis of homologous chromosomes in mouse subspecific hybrids causes hybrid sterility and can be reversed by introducing random stretches of consubspecific sequence (≥ 27Mb) on four chromosomes most sensitive to asynapsis.
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.
Variation in codon usage among functional categories of human genes is not due to selection for translation efficiency, but to differences in intragenic recombination rate, linked to variation in meiotic transcription level.
Building on previous work (Syrjänen, Pellegrini, & Davies, 2014), it is shown that SYCP3 contributes to the architecture of meiotic chromosomes through local bridging interactions that result in large-scale compaction of the chromosome axis.
