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. WebIf the assumptions are not met for a gene, the population may evolve for that gene (the gene's allele frequencies may change). Mechanisms of evolution correspond to violations of different Hardy-Weinberg …

WebNatural selection is one of the basic mechanisms of evolution, along with mutation, migration, and genetic drift. Darwin's grand idea of evolution by natural selection is relatively simple but often misunderstood. To see how it works, imagine a population of beetles: There is variation in traits. For example, some beetles are green and some are Webexample of disruptive selection in human evolution. Despite its rarity, however, disruptive selection may be very important for the emergence of species. After suitable time, …

WebMutations are changes in the information contained in genetic material. For most of life, this means a change in the sequence of DNA, the hereditary material of life. An organism's DNA affects how it looks, how it behaves, its physiology — all aspects of its life. So a change in an organism's DNA can cause changes
