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.

Animals can be classified according to different physical characteristics, such as body covering (e.g., hair, fur, feathers, scales, shells), body shape (e.g., two main features, three main features), appendages (e.g., arms, legs, wings, fins, tails), and method of movement (e.g., walking, crawling, flying, swimming).
Answer:
The new research suggests that Earth's water came from both rocky material, such as asteroids, and from the vast cloud of dust and gas remaining after the sun's formation, called the solar nebula.
Explanation:
I hope this counts - cell wall! helps keep most materials out but allows specific materials to pass through. animal cells do not have a cell wall
