MEIOTIC MISHAP. “Environmental stress often triggers unreduced gamete production, suggesting that unreduced gametes may facilitate polyploid speciation in response to changing environments. Thus, although unreduced gamete formation may be a meiotic mishap, we suggest that unreduced gametes can be more explicitly considered as a mechanism for evolutionary speciation that should be measured and tested across and within lineages for exaptive evolution (a feature with evolutionary utility that has not arisen under conventional selective pressure) and evolvability (the capacity to generate adaptive genetic variation).”
