Because of genetic recombination and this is done in three ways. The independent orientation of chromosomes at prometaphase, crossing over and the process of random fertilization all insure a good recombination of genetic material.
That organisms vary, by sexual recombination or mutation. That some organisms will be better at survival and reproduction so that their alleles are passed on to progeny and these causes a change in frequency of these alleles over time which is the definition of evolution.
Speciation adds to biodiversity. Hence it affect the evolution of best suited forms to come up.
For a mutation to affect evolution it must occur in the dominant allele. This allele is what is passed on.

Genetic variations are produced by mutations and sexual recombination
Without it you and everyone else would be clones. If a disease will kill you, it will kill all.

Evolution is the change of allele frequency in a population of organisms. So, for a characteristic to affect evolution it must be heritable, genetically so, it must be selected for, or be the result of recombination processes and it must be in the germ line where it is passed to future generation of, hopefully, reproductively successful organisms who leave enough decedents to change the allele frequency in the populations gene pool over time.

The term coevolution (affect) is used to describe cases where two (or more) species reciprocally affect each other's evolution. So for example, an evolutionary change in the morphology of a plant, might affect the morphology of an herbivore that eats the plant, which in turn might affect the evolution of the plant, which might affect the evolution of the herbivore and so on.
Vegetative reproduction is most common in plants, however, sexual reproduction is the essence of evolution as it brings genetic recombination.
No

Linked that closely these genes can travel down the generation not being crossed over or subjected to recombination in any way. Mutation in one or the other may break this linkage, but that is not as statistically likely as the non-recombination events in sex cells over many generations.
