Evolutionary ‘arms race’ may help keep cell division honest

Certain proteins may have evolved to tamp down 'cheating' during meiosis, the cell-division process that gives rise to eggs and sperm. While chromosomes can tip the scales in their favor of winding up in an egg, the team's new work identifies a mechanism that keeps the odds closer to 50-50, possibly reducing the likelihood that chromosomal abnormalities will arise during egg production.
