Difference between Geitonogamy and Xenogamy

Geitonogamy may be characterised as a sort of self-pollination wherein fertilisation of crops can occur by transport of pollen through one single flower of some other bloom of the very same crop by breeze or pollinators. The benefits of self-pollination include that it is a guaranteed form of fertilisation that does not rely on external circumstances. It includes the lowest wasting of pollen and hereditary integrity is preserved. The fundamental qualities of crops may be kept and could be employed to proliferate the enhanced range of herbs. There are several downsides to geitonogamy. 

Geitonogamy happens among individuals which are air pollinated but it may be quite a frequent cause of self-fertilised seeds with organisms that are conscience. Furthermore, in unisexual gymnosperm geitonogamy kind of self-pollination is found. Self-implantation is sometimes termed autogamy. In this case, the merging of two gametes can occur which originates through one specific individual.

Xenogamy is indeed the transference of grains from the anther from one bloom of a species towards the stigma of yet another blossom of a separate species. It acts as a cross-pollination mechanism yet is genetically comparable to autogamy. This is a cross-pollination process. The pollen has a comparable genomic construct.

Definition

Geitonogamy: Geitonogamy is the process of transmission of pollen towards the stigma of bloom of the very same species.

Xenogamy: Xenogamy is the process of transfer of pollen grains to the stigma of some other bloom of a plant sample.

Geitonogamy and Xenogamy: Differences

1. Differences based on flowers

Geitonogamy: In the case of Geitonogamy, the flowers are mostly similar from a genetic point of view.

Xenogamy: In the case of Xenogamy, the flowers are mostly different from a genetic point of view.

2. Differences based on Genetic Aspect

Geitonogamy: This is a kind of self-pollination technique.

Xenogamy: This is a kind of cross-pollination technique.

3. Differences based on Seeds

Geitonogamy: In the case of geitonogamy, the seeds involved are identical from a genetic point of view.

Xenogamy: In the case of xenogamy, the seeds involved are non-identical from a genetic point of view.

4. Differences based on the Number of Species Involved

Geitonogamy: In the case of geitonogamy, only one plant is required.

Xenogamy: In the case of xenogamy, two plants are involved that are genetically different.

5. Differences Based on Advantages of Geitonogamy and Xenogamy

Geitonogamy: Reduced wasting of pollen granules and integrity of organism preserved since evolutionary divergence doesn’t really vary. Pollinating substances and external entities such as water, and the wind is not engaged in self-pollination. Mutant elements are deleted.

Xenogamy: Superior grade of nutrients supplied. There is indeed a range of alleles inside the genus. Offspring demonstrate stronger protection against illnesses.

Dichogamy is the maturity of sexual characteristics i.e. yet another stigma inside the crops at separate periods. Dichogamy could be Interflora and intrapleural. In diclinous plants, it appears amid petals. So, this is why the floral apparatus encourages cross-pollination.

Conclusion

Hence from the above discussion, it is clear that; Geitonogamy is a kind of autogamy since pollen granules transported are exactly identical. It allows the acquisition of pollen from the other as well with one bloom to the stigma of some other bloom of the very same species. It is effectively cross-pollination since fertilising molecules are necessary. It enables the distribution of genetically related propagules to the stigma.

Xenogamy is a kind of allogamy. It includes the transportation of pollen granules from the anther from one species towards the stigma of that other species. It is a sort of cross-pollination. Pollinating substances are necessary for such a sort of fertilisation. It enables the distribution of genetically diverse pollen to the stigma.
