4 0

A change at the molecular level leads to a change in phenotype if the change happens in the DNA of organisms.

<h3>What is mutation?</h3>

It is a change to the genome of organisms.

A change to the DNA sequence of organisms may or may not manifest in the morphological appearance of organisms.

A change to the DNA sequence of organisms means that entire new proteins would be synthesized and only in this way can the phenotype of organisms be altered as a result of a change at the molecular level.

Answer:

Red allele frequency will be highest in population II

Population III can undergo bottleneck effect

The frequency of the brown allele will least likely be altered in the population I

Explanation:

Population I -

Total population - $670$

Brown birds - $603$

Red birds - $67$

Population II

Total population - $100$

Brown birds - $90$

Red birds - $10$

Population III

Total population - $30$

Brown birds - $27$

Red birds - $3$

Frequency of red birds in population I

$\frac{67}{670} = 0.1$

Frequency of red birds in population II

$\frac{10}{90} = 0.11$

Frequency of red birds in population III

$\frac{3}{30} = 0.1$

Red allele frequency will be highest in population II and it will be equal to $\sqrt{0.11} = 0.33$ as compared to $0.31$ in case of population I and III
