Does asexual reproduction increase the chances of natural selection?

No, it doesn't. It doesn't help to form new species since the offspring are clones and exactly the same.

What is the importance of sexual reproduction among species?
Sexual Reproduction is superior to asexual reproduction mainly for the reason that it involves gametes from two different individuals. This improves chances of variations which is the basis of heredity and evolution. In asexual reproduction, only one parent's gamete is involved. Thus the offspring is liable to have all the characteristics ( and defects) of the parent which doesnot allow variation.
What does the reshuffling of chromosomes in sexual reproduction increase?
Sexual reproduction allows a species to develop the means necessary to adapt to ever-changing environment conditions, so long as the change isn't too drastic or happen too suddenly.
Which is better mode of reproduction sexual or asexual and why?
Asexual reproduction is favourable if horizontal gene transfer can make up for the lack of diversity within species. Horizontal gene transfer is when two mature organisms can switch or share different genes. (Many bacteria and archea can do this) Horizontal gene transfer is quite difficult for multi-cellular organisms, so sexual reproduction is preferable. The goal of reproduction is to create offspring that will survive in changing environment - so there must be a mechanism to create many different kinds of offspring. Sexual reproduction affords this. However - the optimal form of reproduction is to have the choice to reproduce either asexually and sexually. If there is a disaster (for humans) or a new antibiotic (for bacteria) it may be preferable to reproduce asexually for a while if no other similar species are around. Later, when the population is big enough, sexual reproduction can begin to recover genetic diversity. (I am assuming that clones don't reproduce with themselves the whole time). This may be the new and improved 'bisexual' of the future.
How does natural selection enhance or reduce the variability of a species?
Natural selection doesn't reduce variation. Variation is regulated by the rate of mutation.Natural selection reduces the chance of bad variation from being passed on and increases the chances for good variation to be passed on.
State the name given to agents that increase the chances of cancerous growth?
Carcinogens or mutagens
Is Sexual or asexual reproduction better for a rapidly changing environment?
Sexual. Sex allows for more variation in offspring thus increasing the chances for survival.
How does natural variation affect evolution?
Natural selection (the driving force of evolution) is the selection of genetic variations by how they effect the organism's chances of survival or reproduction. If they diminish it's chances, the organism or it's immediate offspring die and the gene is gone. If the genetic variations increase it's chances, then it survives. Without genetic variations there can be no evolution. Natural selection is the selection (by environmental pressures) of those variations.

How are artificial selection and natural selection similar?
Natural selection and artificial selection both involve an organism's traits being determined by how much they're favored. Then, the organisms with favorable traits pass those traits on to future generations.However, natural selection is caused by survival; the organisms with traits that increase their chances for survival and reproduction pass on their traits. As for artificial selection, humans purposefully decide which traits (like the most colorful one) of an organism to pass on.The similarity of artificial selection and natural selection is that they both can cause changes in the frequency of population.
When is asexual reproduction advantage?
Asexual reproduction is an advantage in a stable environment. This is because it produces offspring genetically identical to the parent which is already well adapted and suited to the environment. Because the parent is well adapted, all its offspring will be too, increasing their chances of survival in a stable environment. This contrasts sexual reproduction where each offspring is slightly different to the parent and therefore isn't suited exactly the same way as the parent is to the environment. Some of the offspring will adapt and survive but the others won't. Sexual is also best for changing environment Asexual is best for stable environment Asexual reproduction is also advantageous when species numbers are low, as the requirement of a mate to reproduce doesn't exist.
How the genetic monotony overcome by the sexual reproduction?
Sexual reproduction is important to avoid genetic monotony the result of asexual reproduction where generation after generation exactly identical progeny develops sexual reproduction produces an endless variety of organisms because each organism develops from a unique set of characters coming from different parents.
What does the reshuffling of chromosomes in sexual reproduction increase?
Sexual reproduction allows a species to develop the means necessary to adapt to ever-changing environment conditions, so long as the change isn't too drastic or happen too suddenly.
How are more pollen grains important in terms of reproductive success?
More pollen grains increase the chances of successful pollination. Successful pollination refers to pollen grains falling on the correct stigma for reproduction to occur.
adaptions?
In evolutionary theory, the physical characteristics, skills, or abilities that increase the chances of reproduction or survival and are therefore likely to be passed along to future generations.
Why is it an advantage for organisms to have more than 1 means of reproduction?
The more offspring an organism has the more they increase their chances of survival. Since offspring die, it is best to have multiples.
How do camouflage and protective coloration adaptations affect an organisms survival and reproduction?
Camouflage and protective coloring adaptations improve an organism's chances of survival and reproduction.
Organisms that reproduce asexually do so because of the what?
1) they know god hates sex, so they decided not to do it.2) asexual reproduction is cloning yourself. Cloning is egoist behaviour.3) organisms that can reproduce both sexually and asexually can do so when a mate is not available, clones of the mother increase the chance of encountering a suitable mate.4) Sexual reproduction only has advantages when there is a significant pressure on the population by parasites. Sexual reproduction ensures a heterogenous genetic makeup in the population, increasing the chances that at least part of it can evade a parasite, thus increasing the chances of survival of the population.But ultimately God will decide who lives or dies, so these theories have nothing to do with that. Honest!
