Well, I don't fully understand your question. I think I know what you're getting at though.
In a system of sexual reproduction, you have genes coming from both an egg and the sperm. Therefore, it'll only contain half the total amount of chromosomes (46 in humans). A sperm will have 23, and the egg will have the other 23. Is that what you meant why the chromosomes are cut out in pairs? If that wasn't your question, please elaborate and I'll return to answer it to the best of my capabilities.

Answer:
India experiences the monsoon season
Explanation:
From the picture, it can be seen that India experiences the monsoon season.
This is evident in that the southwestern summer monsoon is brought into a low-pressure area primarily as a result of great heat moving over the Thar Desert in places like Rajasthan and other nearby areas during summer.
This is illustrated in the picture as wind direction moves inwards at this period, making the moisture-rich wind blowing from the Indian Ocean moves to the low-pressure region, hitting the great Himalayas, and thereby leads to rainfall.
