Cystic fibrosis occurs 1 in every 2,500 individuals.
Using Hardy Weinberg principle,
freq. of recessive allele/ q2 = 1/2500 = 0.0004
Take the square root,
q = 0.02
freq. of dominant allele/ p = q - 1
p = 0.98
freq. of heterozygous individuals = 2pq = 0.04

Therefore, the answer is 0.04, which is C.

Claim and evidence:
puteri [66]

It would happen that the effectiveness of an original vaccine could become less if there was a mutation in the virus that caused the protein spike to change because the antibodies created would not be specific for the new virus.

<h3>What would happen to the mutated virus?</h3>

Vaccines trigger an immune response to fight disease-causing organisms, a mutation in the virus to be fought would change the effectiveness of this immune response, as the specificity would not be the same with the mutant virus.

With this information, we can conclude that The immune response would not be specific for the new virus that caused the protein spike to change.

Answer:

The options

a. sympatric speciation; vicariance

b. allopatric speciation; vicariance

c. sympatric speciation; dispersal

d. allopatric speciation; dispersal

The CORRECT ANSWER IS d.

d. allopatric speciation; dispersal

Explanation:

Allopatric speciation takes place either via dispersal, when some members of a species shifts it's habitat to a separate geographical area which leads to differentiation of the initial group into separate diverse varieties or species(as in our case study).

Allopatric speciation through dispersal could results in multiple speciation leading to an individual original species producing diverse new species; this occurrence is called adaptive radiation.

In some scenario, a population of an individual species disperses all over a region with each locating a separate niche or isolated habitat. In the course of time, the diverse demands of their just formed lifestyles causes multiple speciation events that comes from a singular species.
