Question

Is there any advantages for geitonogamy over autogamy ?

Answer 1

Dear student,Within-flower self-pollination (autogamy) may be advantageous, since it can provide reproductive assurance without much seed or pollen discounting. In contrast, between-flower self-pollination (geitonogamy) provides no reproductive assurance and can cause severe seed and pollen discounting.So it do not have advantage over autogamy.Regards.
