Question

Match List I with List II:

List I		List II
A	Two or more alternative forms of a gene	I	Back cross
B	Cross of F1 progeny with homozygous recessive parent	II	Ploidy
C	Cross of F progeny with any of the parents	III	Allele
D	Number of chromosome sets in plant	IV	Test cross

Choose the correct answer from the options given below:

• A. A-I, B-II, C-III, D-IV
• B. A-II, B-I, C-III, D-IV
• C. A-III, B-IV, C-I, D-II
• D. A-IV, B-III, C-II, D-I

Answer 1

The Correct Option is C

To resolve this issue, establish accurate pairings between terms in List I and their corresponding definitions in List II. The following analysis details each term and its correct match:

List I	Definition	List II
A	Two or more alternative forms of a gene	III
B	Cross of F1 progeny with homozygous recessive parent	IV
C	Cross of F progeny with any of the parents	I
D	Number of chromosome sets in plant	II

1. Item A: 'Two or more alternative forms of a gene' is identified as an allele. Therefore, item A aligns with option III.
2. Item B: 'Cross of F₁ progeny with homozygous recessive parent' is defined as a test cross. Consequently, item B matches with option IV.
3. Item C: 'Cross of F progeny with any of the parents' is termed a back cross. Hence, item C corresponds to option I.
4. Item D: 'Number of chromosome sets in plant' is associated with ploidy. Thus, item D pairs with option II.

The definitive matching is as follows: A-III, B-IV, C-I, D-II
