What is advantage of asexual reproduction in any kind of tree?
930792
One main advantage is the ability of the offspring to take advantage of the parent's resources while the young tree is growing. Trees growing from seeds are limited to the resources in the seed to get their start; trees from root-shoots can borrow from the parent until they can make it on their own. Think of a redwood: most of their reproduction is asexual. Their seedlings have little chance in the deep shade of a forest, but when root-sprouts can take advantage of resources from an already-mature tree getting light in the canopy, the sprouts can grow 3 feet a year.\nSome trees can also root-sprout or stump-sprout if they are cut or fall down. That's another big advantage--to be able to reproduce almost after you're dead.\nAnother advantage is that an asexually reproducing tree is assured of a good environment for its offspring--if it has enough energy to reproduce, it must be doing well. Of course that advantage is shared by non-dispersing sexually reproducing trees.

Some plants can reproduce asexually using their stems, roots or by producing bulbs. These plants can also have flowers and reproduce sexually.

Evolution of reproduction. Nature finds its way.

The pros are being able to learn about the effects of different genetic patterning.  Perhaps solving some questions of nature vs. nurture.\n\nThe cons very from reducing genetic variety, which can lead to weakness of the cloned species because a certain stressor could knock out the whole bunch if they are genetically the same.  Every time something is copied usually something is lost.  Also cloned species can have unknown effect on other species. For example, some form of genetically engineered corn which is resistant to pests also kills off monarch butterflies that consume a portion of the plant.

Not exactly clear on your question, but I think it's yes.  For those organisms that don't exchange anything and just produce asexually, they don't have sex and they just split into 2 identical copies.

An existing organism is born with certain genes.  Those genes determine how that organism will develop during its life.  Those genes cannot change ... there is no mechanism in life to alter the genes for the entire organism (individual cells yes ... e.g. cancer, but not the entire organism).\n\nSo even if that single organism lived for centuries (like a redwood tree), it cannot change (evolve) in ways not dictated by its genes.\n\nNew life (offspring) is a brand new set of genes ... a new mixture from each of its parents.  \n\nSo each offspring can be different from either one of its parents ... better or worse in some characteristics, or all characteristics, from either parent.\n\nSo over the entire group of individuals in a species ... you have many individuals with slight improvements over their parents.  Those will produce more offspring than those who have fewer improvements (or are slightly worse adapted) than their parents.\n\nThe result is evolution.  Many many tiny improvements in genes, over many many generations.  You cannot have that evolution, without the opportunity for new genes with every new life.

To my knowledge, there are no snakes that reproduce mostly through asexual means.  Numerous snakes are known to be able to reproduce by parthenogenesis, producing little clones of the mother, but never as a primary mode of reproduction, usually only if males are not available.

Advantage_easy sex.\nDisadvantage-won't last, STDs, reputation of seeing sluts, etc.

all off spring plants will be similar to that of parent plant in all characters .even the delicate characters like taste ,colour shape of fruit ,smell are 100%similar.\n\nthis true to type nature is obtained by going for vegetative or asexual propagation methods like budding, grafting, stem cuttings, root cuttings, leaf cuttings etc.

what do you mean by yield? do you mean percentage success? the advantage of cuttings is always: you know what you will get (identical to the plant the cutting came from) and they will almost always mature (flower/fruit) sooner than a seedling.

are you asking about DNA extraction or plant (apple tree) cross-breeding?

It is E\n\nThe reason: \na) Reproductive variations lead to the "better producer" making more offspring and thus leading to more chances for their offspring to reproduce.  For this one, think of gorillas...the dominant Male (silverback) will mate with the females so it is his offspring who carry the genetics into the next generation, and the other males in the group dont pass on their genes. \n\nb) There has to be some offspring that simply don't survive...this is the whole "don't interfere and let nature take its course" thing.  This means that after the "unhealthy" individuals die, the rest (on average) will be better suited to their environment.  Think of it like this... a  human family has three babies but one of them dies; the one that died may have had a defect that shouldn't have been passed on.  Since the parents had two other babies, they have replaced themselves in the population so there will not be a net loss of population when they eventually die. \n\nc) There has to be variations in the genetics of the offspring.  This is due to the fact that for us to become better suited to our environment, there has to be a change in our genetics to produce that change.  If we were exactly like our parents, no changes could occur.\n\nd) Inheritance is hugely important.  Think about it like this: If a beneficial change develops (such as opposable thumbs), what good would it be if it couldnt be passed on to the next generation?  There must be a mechanism to pass the benefit on.  \n\ne) Even though there have been many catastrophic events that have allowed for natural selection, it is not required.  A large eruption may cause the animals who can eat more diverse variety of plants to do better than ones that can't but they may be able to out-compete the other animals anyway.

As a species, sex is necessary to propagate the species.  It's not necessary for an individual to have sex, however.  There are health benefits, certainly, but if it were required as air, food and water are required, there would be a whole lot of ailing nuns and priests out there.

I am not sure what you mean by uni-sex in biology....\n\nIn biology, sexual reproduction is not said to have been started with only females per se! Uni sexual is not the same as hermaphroditic either. Monoecious and dieocious are the usual terms. Monoecious means hermaphrodite and dioecious means separate sexes. But reproduction can be either sexual or asexual (and sometimes some organisms do both, like, mosses, liverworts, ferns with alternation of generations.) \n\nThere are a few species of animals who have only females, though....at least 22 species of parthenogenic lizards identified last I checked! They lay eggs, mate like "lesbian lizards" without sperm and have babies. Wild!\n\nHowever, a "male" is usually described in biology as any organism that makes "sperm" gametes, so in that case, hermaphroditic organisms like most flowering plants (sperm is in pollen) have males as PART of the often hermaphroditic flower known as the stamen.  (some flowers are dioecious) So males are found in plants or animals.  In fact the anther is the pollen producing part of the stamen and is sorta comparable to the testes of the animal. In fungus there are opposite strains of hyphae that reproduce "sexually" but not with gametes and they are described as + and - branches, which some claim are m-f, but it is still considered sexual reproduction, whereby genetic information is exchanged and a genetically DIFFERENT offspring is produced. Asexual produces gentically identical offspring-clones. Bacteria usually reproduce asexually, but sexual conjugation can occur (sexual) in bacilli. Paramecium are the most famous for their sexual reproduction-conjugation too. In the cases of fungi, bacteria, paramecia, however, the gender is not considered even though it is considered SEXUAL. So what biologists consider as very "primative" organism are capable of sexual reproduction.

The main advantage of sexual reproduction is that it can produce much more variation in the offspring, which gives natural selection more to work with.  This allows faster adaptation of future generations to changes in the environment, or to allow future generations to explore different environments.\n\nThe main disadvantage is that it requires individuals to find sex partners.  So a very sudden catastrophe that causes scarcity of individuals, could cause extinction, where an asexual organism might be able to rebound.

Sexual reproduction in plants is described in Wikipedia as;\n\nIn flowering plants, a stamen produces gametes called pollen grains, which attach to a pistil, in which the female gametes (ovules) are located. Here, the female gamete is fertilized and develops into a seed. The ovary, which produced the gamete then grows into a fruit, which surrounds the seed(s). Plants may either self-pollinate or cross-pollinate.\n\nYou can also find out more here \nhttp://en.wikipedia.org/wiki/Plant_sexuality

The advantage is seen in the fishes who could slightly breathe through their skin.  When the pond dries up millions of times over hundreds of millions of years the descendants with better breathing could eventually stay ashore and ponder these questions.  The advantage of asexual reproduction is that you don't have to be cute.
