Question

How can the bottleneck effect

result in the development of a
new species?
A. Allele frequency decreases and is so
different from the original population that
speciation occurs.
B. Allele frequency increases so much that
nothing changes within the population.
C. Allele frequency stays exactly the same
resulting in no change in the population.

Answer 1

A. Allele frequency decreases and is so different from the original population that speciation occur.

Step-by-step explanation:

Bottleneck effect is a change in allele frequency following a dramatic reduction in the size of a population. It means the population decreases so much that there are few species left in the population.
