The probability that at some point in the future allele k will drift to a frequency of 1.0 is 0.5 because genetic drift is a random and non-directional mechanism of evolution that significantly alters the gene or allele frequency in any population.
<h3>What is Genetic Drift?</h3>
Genetic drift may be defined as a mechanism of evolution in which allele frequencies of a population changes over generations due to chance (sampling error). It is more effective in small populations.
The outcome of genetic drift can not be predicted because it is a random and non-directional mechanism of evolution. It is possible that it fixes the allele k and makes its frequency 1.0, while it also alters the frequency of other alleles and makes the allele k eliminated from the given population. It is a process that depends on the phenomena of chance.
Therefore, it is well described above.

1) Homeostasis describes the carefully maintained optimal physiological conditions in our body, regardless of our outside conditions. Viruses can disturb this homeostasis by growing in our body, where they do not below, and producing toxins. Viruses are very much like the effect of a storm at sea on a sailing ship, as the ship is unable to rect as normal to feedback controls to maintain a course.
2) The feedback loop in a sailing ship to maintain it's course would be the ships captain checking the course and detecting that the ship is off course, giving a signal for the ship's rudder and sails to be adjusted. The wind that first pushed the ship off course then plays a role in bringing the ship back on course.
The answer is C. This is because, with every mitotic division,
the cell population doubles because each cell gives rise to two daughter cells.
Therefore, mathematically, after 4 division of one cell, there will end up with
16 cells (2^4).
