Question

Match List-I with List-II:

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

Hint:

Mendel's choice of pea plants was brilliant - they have clear contrasting traits and can self-pollinate.

Answer 1

The Correct Option is B

Pisum sativum (Garden pea): Mendel's laws of inheritance (A
III)
Mirabilis jalapa (Four o'clock flower): Incomplete dominance (B
I)
Neurospora: Model organism for biochemical genetics (C
II)
Lathyrus odoratus (Sweet pea): Complementary gene action (D
IV)

Answer 2

Conceptual approach:
Instead of matching by list position, recall each organism's landmark contribution to genetics. Garden pea, Pisum sativum, is the classic material behind Mendel's laws of segregation and independent assortment. The four o'clock plant, Mirabilis jalapa, is the textbook example of incomplete dominance, where pink flowers arise from a blend of red and white alleles. Neurospora crassa, the bread mould, became the model organism that established the one-gene-one-enzyme concept in biochemical genetics. Sweet pea, Lathyrus odoratus, is remembered for demonstrating complementary gene action in flower colour inheritance.
Matching each organism to its genetic concept gives A-III, B-I, C-II, D-IV.
