In grasshopper, the sex-determination mechanism is:
AZW type
BXO type (males XO, females XX)
CHaplodiploid
DXY type
Answer & Solution
Correct answer: B. XO type (males XO, females XX)
Grasshopper: **XO type** — females have a pair of X chromosomes (XX + autosomes), males have only one X (XO + autosomes). Males produce two types of sperm (X-bearing and no-X-bearing) → male heterogamety.
