Sex determination ratio in a organism is given by `(X)/(A)=1.5,` then organism will be :-

Options

A. male
B. female
C. super female
D. intersex

Answer

To solve the question regarding the sex determination ratio in an organism given by \( \frac{X}{A} = 1.5 \), we will follow these steps:

### Step 1: Understand the Variables
- \( X \) represents the number of X chromosomes.
- \( A \) represents the number of sets of autosomes.

### Step 2: Apply the Genic Balance Theory
- The Genic Balance Theory, proposed by C.B. Bridges in 1922, states that the sex of an organism can be determined by the ratio of X chromosomes to the number of sets of autosomes.

### Step 3: Analyze the Given Ratio
- The given ratio is \( \frac{X}{A} = 1.5 \).
- According to the Genic Balance Theory:
- If \( \frac{X}{A} = 1.0 \), the organism is a normal female.
- If \( \frac{X}{A} = 0.5 \), the organism is a normal male.
- If \( \frac{X}{A} \) falls between 1.0 and 0.5, the organism exhibits an intersex phenotype.
- If \( \frac{X}{A} = 1.5 \), the organism is classified as a super female.

### Step 4: Conclusion
- Since the ratio \( \frac{X}{A} = 1.5 \) indicates that the organism is a super female, we conclude that the answer to the question is **super female**.

### Final Answer
The organism will be a **super female**.
