CAIE IGCSE Biology EXTENDED 16.3.9 Self-pollination as the transfer
Practise defining self-pollination, distinguishing it from cross-pollination, and explaining effects on variation in plant populations.
How this is tested
- state that pollen is transferred to the stigma of the same flower or same plant
- distinguish self-pollination from cross-pollination using same-plant and different-plant cases
- explain reduced variation, homozygosity and poorer adaptation in self-pollinated populations
