Crick suggests that at that stage the formation of the code proceeded by the introduction of new amino acids and by an increase in the precision of recognition of amino acids within classes. Such changes in the code were likely to be disruptive at some protein sites and advantageo ...

In model 1, the presence of an N. crassa-derived gene in the N. tetrasperma genetic background triggers a Bateson– Dobzhansky–Muller incompatibility (BDMI) that induces the additional mitoses. It is well known that when two lineages der ...

The breakpoints of 0.16M SVs were mapped to base pair resolution allowing us to infer that insertion of retrotransposons causes more than half of SVs. Yet, despite their ...

... SUMMARY The life cycle of flowering plants is marked by several post-embryonic developmental transitions during which novel cell fates are established. Notably, the reproductive lineages are first formed during flower development. The differentiation of spore mother cells, which are destined for mei ...

We explore similarities between different chromosomes of the sequence ‘Saccharomyces cerevisiae’. These similarities are characte ...

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.
