... amino acid changes, act as dominant transforming genes in NIH3T3 cells as a result of a constitutive activation of the RET protein (Santoro et al., 1994). This constitutive activation was caused by a ligand-independent dimerization of the protein. Furthermore, Santoro et al. (1994) suggested that th ...

Inbreeding and Inbreeding Depression

... The magnitude of the effect depends on how many harmful recessive alleles are found in the population, and how harmful they are. This is called the genetic load. Genetic load will tend to be lower in species (populations) in which inbreeding has been common in the past (e.g. species with small popu ...

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.
