... adhl-. No ADH activity was detectable when tetrads were first formed after meiosis. Activity was initially detected soon after the tetrads began to break apart but before the microspores in the tetrads had completely separated. The transcription of the adhl gene from the haploid genome must thus occ ...

An added advantage to running gels with ethidium bromide is that the mobility of the DNA can be monitored throughout the run until the desired separati ...

There are 47 substitutions or SNPs in strict sense; 22 small indels (insertions and deletions up to 14 bp), from which 12 appear to be in a single base “run” and 5 in more complex microsatellites. In addition, during the positional cloning efforts, we identified 6 micros ...

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.
