bixtya [17]

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

Population III can undergo bottleneck effect because of smaller population size

The frequency of the brown allele will least likely be altered in the population that has highest brown individual , i.e population I
