There are several ways selection can affect population variation:
stabilizing selection
directional selection
diversifying selection
frequency-dependent selection
sexual selection
As natural selection influences the allele frequencies in a population, individuals can either become more or less genetically similar and the phenotypes displayed can become more similar or more disparate. In the end, natural selection cannot produce perfect organisms from scratch, it can only generate populations that are better adapted to survive and successfully reproduce in their environments through the aforementioned selections.

"It will increase the frequency of genetic mutations. *i think this one* It will result in reduced genetic diversity within the species. It will make the species unable to reproduce sexually. It will decrease the life span of the species." - hope that helps not my work tho some one else wrote this
