The Afrikaners are an example of a founder effect that occurs when population and the random decrease in genetic variation is an example of genetic drift.
Explanation:
When some individuals from a population move to form a new colony, this phenomenon is called founder effect as in case of Afrikaners. The small population or group of individuals forming a new colony may not exhibit the full genetic diversity of the population they were once the part.
The alleles would get expressed in different frequencies than it would have in original population.
There are chances that some alleles are lost or missing also. The new colony formed has small population so chances of genetic drift are very strong.
Genetic drift does not depend upon the benefit or harmful effect of the alleles as it occurs merely by chance sampling. The small population of Afrikaners felt the effect of genetic variation hence strong genetic drift is seen in them.
<span>Poorly worded questions are a frequent cause of errors in polls. When questions are worded in strange ways, people often misunderstand them and respond incorrectly to the question causing an error in the polling data. Often, people respond oppositely to what they would normally say due to misinterpretation.</span>

Explanation:
Compartment syndrome is a painful condition in which there is an increased pressure within muscles or one of the body's compartment, resulting in insufficient blood supply or blood flow to tissue around or within the area.
It majorly affects the compartments of the leg or arm, and could be acute or chronic.
An acute compartment syndrome requires a surgical emergency, while the chronic is not a medical emergency.
Some of the symptoms are severe pain, numbness and pale color of the affected area.
