Answer 2

Answer:

(4) Nucleus

Explanation:

The sperms of grasshopper lack the chromatin material in 50% of the sperms. The chromatin material is the one responsible for carrying the genetic information from the parent to the offspring. The nucleus is the one carrying the chromatin material.

The sexes in grasshopper are distinguishable by observing their posterior ends. The posterior ends of the males are round whereas in females it is round, due to the presence of ovipositor.
