Show Hint

Remember the difference:

  • II & III
  • III & IV
  • I & IV
Show Solution

The Correct Option is D

Solution and Explanation


Step 1: Analyze Mendel's Seven Traits:
We must verify each row against the standard dominant and recessive traits studied by Gregor Mendel in Garden Pea (\textit{Pisum sativum}).
Row I: Seed Shape.
Dominant: Round. Recessive: Wrinkled.
Status: Correct.
Row II: Pod Colour.
Dominant: Green. Recessive: Yellow.
(The table lists Yellow as Dominant, which is incorrect).
Status: Incorrect.
Row III: Flower Position.
Dominant: Axial. Recessive: Terminal.
(The table lists Terminal as Dominant, which is incorrect).
Status: Incorrect.
Row IV: Colour of seed coat.
In standard NCERT terminology, "Seed Colour" (Cotyledon colour) is Yellow (Dominant) and Green (Recessive). "Seed Coat Colour" is usually Grey/Violet (Dominant) and White (Recessive). However, in many competitive exam contexts, "Seed Coat Colour" is sometimes used loosely to refer to the Seed Colour (Cotyledon). If we treat it as Seed Colour, Yellow \textgreater Green. Given that II and III are definitely false, and I is definitely true, we must look for an option containing I. The options are "I & II" (False) or "I & IV". Since II is strictly false, IV must be accepted as correct in this specific context (likely referring to seed/cotyledon colour). Status: Accepted as Correct for this question.

Step 2: Select the Option:
The correct rows are I and IV.
