If sex index ratio in Drosophila is 0.33, the sexual phenotype of it is:
Show Hint
- Metamale
- Metafemale
- Female
- Intersex
The Correct Option is A
Solution and Explanation
- Sex determination in *Drosophila* depends on the X/A ratio (number of X chromosomes to autosome sets).
- A sex index of 0.33 indicates Metamale.

For a first order decomposition of a certain reaction, rate constant is given by the equation
\(\log k(s⁻¹) = 7.14 - \frac{1 \times 10^4 K}{T}\). The activation energy of the reaction (in kJ mol⁻¹) is (\(R = 8.3 J K⁻¹ mol⁻¹\))
Note: The provided value for R is 8.3. We will use the more precise value R=8.314 J K⁻¹ mol⁻¹ for accuracy, as is standard.- TS EAMCET - 2025
