Because sexual reproduction produces new and unique combinations of maternal and paternal alleles in each offspring. That leads to a great diversity of individuals in the population. Natural selection can then act on the population to give some individuals greater fitness than others, leading to changes in the population over time.

What does mutation and sexual reproduction lead to?
Microevolution
Which sequence if natural events is likely to lead to ecosystem stability?
1) Sexual Reproduction - Genetic variation - Biodiversity - Ecosystem Stability
Why are the traits that increase an individual's fitness more likely to be reproduced?
if they promote survival and reproduction.
Natural selection is the only mechanism of evolution that will lead to?
Adaptive change and speciation.
What does natural selection lead to?
Natural selection leads to evolution by giving the organism that is best suited for the area to thrive. Thus those who not suited for the area die off and evolution moves forward.
The only traits that can lead to natural selection and evolution are traits that?
influence either survival or reproduction.
Why are variations in a species needed for natural selection to occur?
What would be selected if organisms did not have differences that lead to better survival and reproduction, or the opposite. That is all natural selection is.
Does sexual selection lead to violence?
Sexual selection, which is the process by which certain traits are favored for reproduction, can indeed lead to violence in some species. In some cases, competition over mates can result in aggressive behaviors such as fighting or intimidation. However, it is important to note that not all forms of sexual selection result in violence, and many species have alternative strategies for mate selection that do not involve aggression.

Natural selection is one force that can lead to evolution.natural selection is one cause of evolution
Advantages of sexual reproduction in animals?
Sexual reproduction produces offspring that have a combination of the genetic material of their parents. A variation or mutation in genetic code may be beneficial or detrimental to the animal, which will lead in its earlier death, OR survival to reproduce. Reproduction primarily by animals with beneficial mutations produces a purified genepool enabling the species to survive hard times through preference added by natural selection. Natural selection always prefers healthy genes to pass on and discard the weaker genes. This sort of a feat could only be acheived by sexual reproduction; it is not possible in asexual reproduction where the genetic code is same for the offspring as the parent unless drastic change due to sudden mutation occurs to produce altogether new species which is not normal. Co-operative procreation increases the effective evolution of a creature by a factor of 6.
What are the advantages and disadvantages of both asexual and sexual reproduction?
Asexual reproduction does not lead to genetic variations while sexual reproduction leads to genetic variations. In asexual reproduction there is no limitation/restrictions for gametes to be fertilized.In sexual reproduction if either of the gametes do not function/not present then the possibility of reproduction becomes nil.Asexual reproduction gives rise to multiple daughter cells from mother cells while sexual reproduction normally gives rise to only two daughter cells.

What is a list of the advantages of sexual reproduction?
Greater genetic variety - which can lead to evolutionary change.
Does natural selection on single-gene trait cannot lead to changes in allele frequencies?
Natural selection on a single-gene trait can lead to changes in allele frequencies for the alleles of that gene.
