4 -- asexual reproduction produces a clone of the organism--genetically it is exactly the same as it's parent. Because of this there is no genetic variation from generation to generation. This neither increases nor decreases the chance for natural selection.

4 is generally the correct answer; however, sometimes 1 is true.

For instance, most new Camellia varieties are produced by asexual reproduction. Mutations can occur in ordinary cells (cancer is an example), not just gametes. If it happens in a growth bud, a "sport" results that has different color or combinations of colors (varigated petals), so you can have a red-flowered Camellia with one branch that has white, pink, or white and pink flowers. This branch is then layered (and tissue cultured) to produce entire shrubs with the same varigation as the branch that sported.

But that is an exception to the rule.

E. while food aspects have been depleted, the climate turns into unfavorable, or guy or woman survival is jeopardized by potential of another unfavorable exchange in residing circumstances, those organisms change to sexual varieties of reproduction. Sexual reproduction ensures a mixing of the gene pool of the species. the transformations latest in offspring of sexual reproduction enable some persons to be extra perfect perfect for survival and grant a mechanism for selective version to take place. to boot, sexual reproduction many times consequences in the formation of a existence point this is able to bear the circumstances that threaten the offspring of an asexual parent. subsequently, seeds, spores, eggs, pupae, cysts or different "over-wintering" ranges of sexual reproduction ensure the survival in the time of unfavorable situations and the organism can "wait out" unfavorable circumstances till a swing back to suitability happens.

Definitely 4.

1is wrong,because no chromosome exchange happens.so 3'wrong too.2 can be true because there is more time for a trait for being extinct or selected.but generally the answer is no.4
