उत्तर
A is false but R is true.
Explanation:
The assertion is false because grasshoppers exhibit male heterogamety, meaning males produce two different types of gametes (half with an X chromosome and half without one) while females are homogametic. The reason is true because grasshoppers use an XO sex-determination system, where females possess a matching pair of sex chromosomes (XX) and males possess only a single X chromosome (XO).
