Question

What is the smallest perfect \(F_2\) population size when four genes are segregating?

• A. \(64\)
• B. \(1024\)
• C. \(256\)
• D. \(16\)

Hint:

For \(n\) segregating genes, smallest perfect \(F_2\) population size is \(4^n\).

Answer 1

The Correct Option is C

Concept:
For \(n\) segregating genes, the smallest perfect \(F_2\) population size is generally calculated as: \[ 4^n \]

Step 1: Identify the number of segregating genes. \[ n=4 \]

Step 2: Apply the formula. \[ \text{Smallest perfect }F_2\text{ population size}=4^n \] \[ =4^4 \]

Step 3: Calculate the value. \[ 4^4=4\times4\times4\times4 \] \[ =256 \] \[ \therefore \text{Correct Answer is (C)} \]
