Advantages:
1. Hybrid vigour is maitained, 2. Chances of aquiring broad genetic base are always there. 3. Process of evolution continues.
Dis-advantages:
1. Seed formation always depend on availability of pollinator
2. Lots of variability leades to heterozygocity and inconsistancy in phenotypes.
3. Mixing of inferior genes takes place if pollinators are not controlled.

∙ 10y agoThe advantage of cross pollination is that the offspring that comes after pollination contains the genes of both father and mother. Therefore the offspring result here is a hybrid and can be stronger than both of they parents and be able to stand even in harsh condition.
Cross pollination results in a stronger and more diverese "gene pool" enabling a species to be more adapatble to changes in the environment.
-----------------------------------------------------------------------------------------------------
Cross-pollination benefits the environment in a number of way. The most obvious is that, it allows for genetic diversity. With cross-pollination spreading good genes throughout a plant population, plants are more likely to survive. Another way cross-pollination benefits the environment is by promoting co-evolution. Co-evolution is a term that refers to a mutually beneficial relationship between two species.
In fact, cross-pollination manages the biological diversity of plants and crops on the planet. It also promises better agricultural yield in commercial orchards because growers can tend to their crops in a more systematic way. Cross-pollination also safeguards and protects bees and butterflies, and in many cases of plant reproduction leads to better crops and stronger crops. This process of natural selection is beneficial for plant species that may otherwise die out.

Can a flower plant have more than one kind of pollination?
No, a flower plant typically has one specific type of pollination method. The method can be either self-pollination or cross-pollination, but a flower is not capable of having multiple types of pollination simultaneously.
In Gymnosperms Male cones usually occur on higher branches and farther from the trunk than the female cones Why would this be?
When pollen from the male cones is released it either falls to the ground by gravity or is dispersed by wind or light breezes. Having the male cone above the female ensures that some pollen will drop onto the female cone via gravity; if the female were above the male no pollen would be able to reach the cone - more a mechanism to ensure self pollination if cross pollination fails. By having the male cones at the our edge of the tree canopy it also improves the pollens chance of being lifted by wind and deposited on a nearby tree (for cross pollination)
What should fruit flies should i cross to get mutant fruit flies other than the white-eyed?
They see better than white eyes furit flies
What is the law of cross cutting relationship?
Prior relationship related answer: Don't be cross cutting across other peoples relationships because you will find your self stuck in the middle. Geological answer: The law of cross cutting relationships states that an igneous intrusion or fault that cuts across another rock stratum must be younger than said stratum.
How is barley pollinated?
Barley is wind pollinated. The male parts of the flower produce a pollen that is blown off by the wind and this then sticks to the female parts of the flower as the breeze blows past them. As with most wind pollinated plants, huge amounts of pollen are produced and breathing this can cause certain people to develop hay fever in the spring/summer.
Why is self pollination better than cross pollination?
Cross pollination results in hybrid seed formation. Hybrids in general are vigorous than self pollinated plants due to additive gene action.
Why is cross pollination better than self pollinating?
it increases genetic diversity, which improves survivorship of the species
Why is cross-pollination of plants better than self-fertilization?
I have heard they are more disease resistant but I can't say for certain.
Why is the stigma a different height than the anthers?
The anthers and stigma occur at different heights to prevent self fertilization and to encourage cross fertilization.
Can a flower plant have more than one kind of pollination?
No, a flower plant typically has one specific type of pollination method. The method can be either self-pollination or cross-pollination, but a flower is not capable of having multiple types of pollination simultaneously.
Compare the self pollination and cross pollination?
Self pollination-The transfer of pollen from a male reproductive structure (an anther or male cone) to a female reproductive structure (a stigma or female cone) of the same plant or of the same flower.Self-pollination tends to decrease the genetic diversity (increase the number of homozygous individuals) in a population, and is much less common than cross-fertilization. Many species of plants have evolved mechanisms to promote cross-pollination and avoid self-pollination, though certain plants, such as the pea, regularly self-pollinate.Cross pollination-The transfer of pollen from the male reproductive organ (an anther or a male cone) of one plant to the female reproductive organ (a stigma or a female cone) of another plant.Most plants reproduce by cross-pollination, which increases the genetic diversity of a population (increases the number of heterozygous individuals). Mechanisms that promote cross-pollination include having male flowers on one plant and female flowers on another, having pollen mature before the stigmas on the same plant are chemically receptive to being pollinated, and having anatomical arrangements (such as stigmas that are taller than anthers) that make self-pollination less likely. Insects and wind are the main agents of cross-pollination.
Does a flower need a bee even if it can self-pollinate itself?
Generally speaking cross-pollination (moving pollen from the flower of one plant to the flower of another plant) is considered better than self-pollination. Continual self-pollination of plants results in inbreeding (although sometimes a good thing) and very little genetic divergance. This means that populations of inbred plants are less likily to be able to adapt to climatic or environmental change than those which have a large gene pool.
Why cross-pollination is less likely to happen in this bottle garden than than in an outdoor garden?
if you have an insect in the bottle garden, with the lid shut, it won't be able to breathe/live which means cross-pollination won't happen or is less likely to.
Why do plant species need to promote cross-fertilization rather than self-fertilizationWhy do plant species need to promote cross-fertilization rather than self-fertilization?
Cross fertilization leads to genetic variability which helps in the process of better adaptability and evolution
Why cross pollination produces more genetic variation in the offspring than self pollination produces?
Cross-pollination produces more genetic variation in offspring because it is a different set of DNA that is breeding with the parents DNA to produce the offspring (known as sexual reproduction). In asexual reproduction, the parent plant uses a clone DNA to self pollinate thus creating an exact copy of the parent. Asexual reproduction inhibits genetic variation because the offspring will never develop mutations that could help natural selection.
Why does nature prefer cross pollination?
Cross Pollination can give rise to new breeds or new varieties of plant. Another disadvantage of self pollination is that, if there was an unrequired character for the plant, it will be carried over to the new and younger generations. This all what i know. Hope it helped you.
Why do hybrids that were developed from cross-pollination adapt more to environmental condition than their parent plants?
