The life cycle has all three possible ways of reproduction: sexual (ploidy doubles: syngamy), asexual (ploidy reduces: meiosis of zygote) and vegetative (ploidy does not change: mitotic divisions)

First, it makes the population more diverse, which allows more flexibility to adapt via natural selection. Natural selection means that all organisms are different, but if environmental conditions change, only most adapted will survive. If the population is uniform, it has less chance of survival. Second, it prevents lethal mutations from being transferred to the offspring, because those with the mutations will die and not pass on genes
