Answer:
C. Only one allele appears for that gene in that population.
Explanation:
This totally explains what happens during gene fixation because when it happens in a small population, it tends to make one of its allele to appear for the said gene.
Furthermore, fixation can be explained as the change in a gene pool from a situation where there exists at least two variants of a particular allele to a situation where only one of the alleles is left. In the absence of mutation, any allele must eventually be fixed or lost completely from the population. Whether a gene will ultimately be lost or fixed is dependent on selection coefficients and chance fluctuations in allelic proportions.

Answer:
<em>Test group is a group that is modified or </em><em>changed by the researcher </em><em>and is then compared to the </em><em>experimental group while carrying out an experiment. </em>
Explanation:
While observing the data of the test group, it has to be compared with the control group to see if there is any effect of the treatment on the test or not. The control can be positive or negative or both to which the test group is compared.
