Question

Given below are two statements:
Statement I: Hybrids are heterozygous and homogenous.
Statement II: Pure lines are heterozygous and heterogeneous.
In light of the above statements, choose the most appropriate answer from the options given below:

• A. Both Statement I and Statement II are true
• B. Both Statement I and Statement II are false
• C. Statement I is correct but Statement II is false
• D. Statement I is incorrect but Statement II is true

Hint:

Hybrids: Heterozygous and homogeneous.
Pure lines: Homozygous and homogeneous.
Multilines: Homozygous and heterogeneous.

Answer 1

The Correct Option is C

Step 1: Understanding the Question:
This question tests knowledge of the genetic constitution of hybrids and pure lines.

Step 2: Detailed Explanation:
Statement I:
Hybrids (e.g., single cross F1) are heterozygous and homogeneous (uniform).
This is correct.
Statement II:
Pure lines are homozygous and homogeneous.
They are not heterozygous.
Thus, this statement is false.

Step 3: Final Answer:
Thus, Statement I is correct but Statement II is false, which corresponds to option (C).
