Match the items of Column - I with Column - II:Column-I ...
Explanation:

XX-XO method of sex determination:
- In this method, females have a pair of XX chromosomes, while males have a single X chromosome (XO).
- This method is observed in grasshoppers, where females are heterogametic (XX) and males are homogametic (XO).

XX-XY method of sex determination:
- In this method, females have a pair of XX chromosomes, while males have XY chromosomes.
- This method is commonly observed in humans and other mammals, where females are homogametic (XX) and males are heterogametic (XY).

Karyotype-45:
- This refers to Turner syndrome, a condition in females where one of the X chromosomes is missing or partially missing.
- Individuals with Turner syndrome typically have a karyotype of 45,XO, leading to various developmental and physical abnormalities.

ZW-ZZ method of sex determination:
- In this method, females have ZW chromosomes, while males have ZZ chromosomes.
- This method is observed in certain bird species, where females are heterogametic (ZW) and males are homogametic (ZZ).
Therefore, the correct match for the items in Column I with Column II is:
- (a) - (iii) Karyotype-45 (Turner syndrome)
- (b) - (iv) ZW-ZZ method of sex determination
- (c) - (i) XX-XO method of sex determination (Grasshopper)
- (d) - (ii) XX-XY method of sex determination
Thus, option (c) - (a) - (iii), (b) - (iv), (c) - (i), (d) - (ii) is the correct answer.
