In the CBAVD patients in which a mutation is found on both CFTR genes, about 88% of them carry one severe mutation on one CFTR gene and a mild mutation on the second CFTR gene, and about 12% carry mild mutations on both CFTR genes (7). This in contrast to CF, were about 88% of the CF patie ...

Since they have the intrinsic ability to multiply during the transposition process, they are automatically amplified, with a large copy number, restricted only by the carrying capacity of their environment (i.e. the genome) [1]. Transposons often persist in genomes over millions of years. This requi ...

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.
