Are the differences between species due to the effects of many genes, each with a small phenotypic effect, or can differences between species occur as a result of mutations in genes with large phenotypic effects? Are there ...

... Following a WGD, in many cases there is no immediate selective advantage for retaining a gene in duplicate, so one of the duplicates is often lost. Therefore, paralogous regions may share few paralogous genes. Thus, these duplicated regions are often detected by comparison to a related pre-duplicati ...

Microevolution

Microevolution is the change in allele frequencies that occur over time within a population. This change is due to four different processes: mutation, selection (natural and artificial), gene flow, and genetic drift. This change happens over a relatively short (in evolutionary terms) amount of time compared to the changes termed 'macroevolution' which is where greater differences in the population occur.Population genetics is the branch of biology that provides the mathematical structure for the study of the process of microevolution. Ecological genetics concerns itself with observing microevolution in the wild. Typically, observable instances of evolution are examples of microevolution; for example, bacterial strains that have antibiotic resistance.Microevolution over time leads to speciation or the appearance of novel structure, sometimes classified as macroevolution. Macro and microevolution describe fundamentally identical processes on different scales.
