Unreduced gametes: meiotic mishap or evolutionary mechanism?

Abstract excerpt

Unreduced gametes (gametes with the somatic chromosome number) are known to facilitate polyploid formation. Unreduced gametes result from a plethora of different mechanisms across different taxa, suggesting that the ability to produce unreduced gametes has evolutionary utility. Heritable genetic variation for unreduced gamete production has been observed, thereby providing an evolutionary substrate. Unreduced...
