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.
Yoga and strength training are both anaerobic, I believe.
An hour of quick walking would undoubtedly work the cardiovascular system, but an hour seems intense.
Twenty-five minutes of intense interval training would be ideal, as the intensive exercise is interspersed with less intense rest exercises. It has also been shown that this type of training is more efficient than training at a steady level for a longer period (for example, an hour of quick walking).
Bladder, I believe. But they are saying that my answer must be 20 Characters long...
A simple example to illustrate genotype as distinct from phenotype is the flower colour in pea plants (see Gregor Mendel). There are three available genotypes, PP (homozygous dominant), Pp (heterozygous), and pp (homozygous recessive).
