Vedclass · Answer

(D) Geitonogamy is the transfer of pollen grains from the anther to the stigma of another flower of the same plant.Genetically,it is similar to autogamy (self-pollination) because the pollen grains come from the same plant,thus it helps in maintaining homozygosity.Ecologically and functionally,it is cross-pollination because it requires a pollinating agent to transfer the pollen grains.Therefore,the Assertion is incorrect because it claims geitonogamy maintains superiority indefinitely (which is a feature of self-pollination leading to inbreeding depression),and the Reason is incorrect because it claims geitonogamy is genetically cross-pollination.

$A$ : Geitonogamy helps in maintaining homozygosity and superiority of the race indefinitely.
$R$ : It is functionally,ecologically and genetically cross-pollination.
