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: Option A) sensory somatic nervous system-controls skeletal muscles
Explanation:
The somatic nervous system (SNS) is controlled by the brain, and direct conscious or voluntary actions by stimulating the skeletal muscles.
For instance: On seeing an oncoming vehicle, a cyclist will swerve to a safe path. This is a voluntary action, where the skeletal muscles are stimulated by the somatic nervous system to avoid hitting the oncoming vehicle.
