The unusually high frequency of "blue skin" in the area is an example of <u>genetic drift</u>.
<u>Explanation:</u>
It is a shift in the occurrence of an established gene variant within a population due to spontaneous organism screening. The offspring alleles are a composite of those in the parents and opportunity has a role to play in deciding whether or not a given person persists and reproduces.
The bottleneck impact is an interesting instance of genetic drift which take place when the population size is drastically reduced. Occurrences like natural disasters such as earthquakes, floods, fires can destroy a city, eliminate most people and leave a tiny, random assortment of survivors remaining.
The three domain system divides organisms into groups based on similarities in their ribosomal RNA. The three domains in the three domain system are the archaea, eukarya and the bacteria. The domains Archaea and bacteria are all prokaryotic microorganisms, or single-celled organisms whose cells have no nucleus. Domain Eukarya on the other hand has organisms whose cells have nucleus.
For example, insects use wings to fly like bats and birds, but the wing structure and embryonic origin is completely different. <u>These are called analogous structures</u>
