Question:
If sex index ratio in Drosophila is 0.33, the sexual phenotype of it is:
If sex index ratio in Drosophila is 0.33, the sexual phenotype of it is:
Show Hint
Drosophila's sex determination follows the X:A ratio principle. If X/A < 0.5, it results in a metamale.

- Metamale
- Metafemale
- Female
- Intersex

The Correct Option is A
Solution and Explanation
Step 1: Understanding the Sex Index Ratio
- 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.
- 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.

- Study the cross given below:
- Assertion (A): When the two genes in a dihybrid cross are situated on the same chromosome, the proportion of parental gene combinations is much higher than non-parental type.
Reason (R): Higher parental gene combinations can be attributed to crossing over between two genes.
