Web3.) Most forms of selection favour certain alleles and lead to a decrease in overall genetic variation. In summary, if most of the evolutionary mechanisms lead to a loss of genetic diversity over time, what restores it? In particular, where do entirely new alleles come from? The answer to both of these questions is mutation. WebMay 30, 2024 · This can lead to the evolution of entirely new viral strains and greatly increases the genetic diversity of the population.
