Population decline causes an extreme genetic drift called a bottleneck effect. The correct option is C.
<h3>What is bottleneck effect?</h3>
The bottleneck effect describes how a population's size is reduced and then increased, affecting the distribution of genetic variation among its members.
It happened when the population reduced severely. Events like natural disaster or decline of the population.
Thus, the correct option is C) bottleneck effect.

Bone is able to heal more rapidly than muscle or nerve tissue, because both muscle and nerve cells are relatively permanent, while bone is constantly remodeled by osteoblasts and osteoclasts, and thus can be repaired relatively rapidly. Bone building through increased secretion of osteoid is stimulated by the secretion of growth hormone by the pituitary, thyroid hormone and the sex hormones (estrogens and androgens).Osteoblasts can also be induced to secrete a number of cytokines that promote reabsorbtion of bone by stimulating osteoclast activity and differentiation from progenitor cells.Your muscles heal very differently than your bones. you fracture a bone, as long as it is set and fixed in place properly, it will tend to heal so thoroughly that it will become stronger than it was before the fracture! Your muscles however, do not actually heal with muscle tissue, but with "foreign" substances including collagen. The resulting scar tissue is weaker, less elastic, and highly prone to re-injury. Once a muscle is damaged, it can become the source of a great deal of pain. Muscle healing can require several months, and muscle scarring is often permanent. Nerve tissue healing is slowest, because nerve cells are not readily regenerated. The duration of the regenerative process varies and may require 6-18 months, depending on the length of the nerve and the site of the lesion. Although the commonly quoted regeneration rate is 1 mm/d, this figure varies considerably and can be used only as a rough estimate. Occasionally, very early signs of recovery may be present, which are thought to be due to so-called pioneer axons, which quickly navigate the pathway to the target tissue ahead of most nerve fibers
Hi,
I think the answer you're looking for is already in the question you submitted. However, I disagree that a frameshift could result from the mutation because frameshifts would only happen if there were insertions or deletions in the sequence. For your question, this is an example of a simple point mutation/nucleotide base substitution, and would only result to either a missense or a nonsense mutation. Depending on the bases flanking your mutation, this results to transcribing a different sequence of RNA leading to translating either a different amino acid or a stop codon.
