Question

Match List-I with List-II
List-I (Incubation period (days)):
(A) 28
(B) 35
(C) 54
(D) 16
List-II (Species):
(I) Japanese quail
(II) Guinea fowl
(III) Muscovy duck
(IV) Emu
Choose the correct answer from the options given below:

• (A) - (III), (B) - (IV), (C) - (II), (D) - (I)
• (A) - (I), (B) - (II), (C) - (III), (D) - (IV)
• (A) - (I), (B) - (II), (C) - (IV), (D) - (III)
• (A) - (II), (B) - (III), (C) - (IV), (D) - (I)

Hint:

To remember incubation periods:
- Chicken = 21 days
- Quail = 16 days
- Duck/Turkey/Guinea Fowl = 28 days (except Muscovy, which is 35 days)
- Emu = 54 days (nearly 8 weeks)

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
The incubation period is the time required for an embryo to develop inside an egg under optimal temperature and humidity before hatching.
This period varies significantly across different avian species.
Detailed Explanation:
Let us match each incubation period with the corresponding poultry species:
- (A) 28 Days: This is the typical incubation period for several species, including the domestic turkey, peafowl, and Guinea fowl (II).
- (B) 35 Days: While most duck breeds require 28 days of incubation, the Muscovy duck (III) is an exception, requiring 35 days for its embryos to hatch.
- (C) 54 Days: Ratites have much longer incubation periods due to their large egg size. The Emu (IV) egg typically requires an incubation period of 50 to 56 days (averaging around 52--54 days).
- (D) 16 Days: Small avian species have shorter incubation times. The Japanese quail (I) has an incubation period of 16 to 18 days (averaging 16 days).
Combining these individual matches:
\[ (A) \rightarrow (II), \quad (B) \rightarrow (III), \quad (C) \rightarrow (IV), \quad (D) \rightarrow (I) \] This matches option (D).

Step 2: Final Answer:
The correct match is (A) - (II), (B) - (III), (C) - (IV), (D) - (I).
