Question

Match List-I with List-II: 

List-I		List-II
(A)	Birds	(II)	ZZ-ZW type
(B)	Human beings	(III)	XX-XY type
(C)	Grasshopper	(IV)	XX-XO type
(D)	Honey bee	(I)	Haplodiploidy

• A. \(A\text{-II},\ B\text{-IV},\ C\text{-III},\ D\text{-I}\)
• B. \(A\text{-II},\ B\text{-III},\ C\text{-IV},\ D\text{-I}\)
• C. \(A\text{-III},\ B\text{-II},\ C\text{-IV},\ D\text{-I}\)
• D. \(A\text{-I},\ B\text{-IV},\ C\text{-III},\ D\text{-II}\)

Hint:

Remember:
• Humans \(\rightarrow\) XX-XY
• Birds \(\rightarrow\) ZZ-ZW
• Grasshopper \(\rightarrow\) XX-XO
• Honey bee \(\rightarrow\) Haplodiploidy

Answer 1

The Correct Option is B

Concept: Different organisms exhibit different mechanisms of sex determination. Common systems include:
• XX-XY type
• XX-XO type
• ZZ-ZW type
• Haplodiploidy

Step 1: Matching Birds. Birds show: \[ \text{ZZ-ZW type} \] where:
• Male \(=\) ZZ
• Female \(=\) ZW Thus: \[ A \rightarrow II \]

Step 2: Matching Human beings. Humans possess: \[ \text{XX-XY type} \] where:
• Female \(=\) XX
• Male \(=\) XY Thus: \[ B \rightarrow III \]

Step 3: Matching Grasshopper. Grasshopper exhibits: \[ \text{XX-XO type} \] where males possess a single X chromosome: \[ XO \] Thus: \[ C \rightarrow IV \]

Step 4: Matching Honey bee. Honey bees show: \[ \text{Haplodiploidy} \] where:
• Fertilized eggs \(\rightarrow\) Diploid females
• Unfertilized eggs \(\rightarrow\) Haploid males Thus: \[ D \rightarrow I \]

Step 5: Determining the correct combination. Therefore: \[ \boxed{ A\text{-II},\ B\text{-III},\ C\text{-IV},\ D\text{-I} } \] Hence, the correct answer is: \[ \boxed{(B)\ A\text{-II},\ B\text{-III},\ C\text{-IV},\ D\text{-I}} \]
