... Inducible genes usually encode for enzymes that are involved in catabolic pathways. In other words, these inducible are repressed most of the time (off most of the time) and are expressed only when their substrate (to be degraded or hydrolyzed) of these catabolic enzymes is available. This substrate ...

... However, tasters vary greatly in their sensitivity to PTC. And while the PTC gene has about 85% of the total influence over whether someone is a taster or a non-taster, there are many other things that affect PTC tasting ability. Having a dry mouth may make it more difficult to taste PTC. What you a ...

However, given that human and chimpanzee DNA are between 98-99% identical, you can imagine how tiny the differences are between DNA from two people. However, there ...

Relative fitness is greater than 1.0 for birds with bigger beaks, and less than 1.0 for birds with smaller beaks. On that graph the slope is b=0.4. There are several advantages for measuring selection from the slope ...

A dominant allele is one that is expressed in the phenotype even if only one copy is present in the genotype—that is, even if t ...

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.
