- D.Pod – Inflated or Constricted
Correct Answer
(B) Trichomes – Glandular or non-glandular
Solution & Explanation
Answer: (B) Trichomes – Glandular or non-glandular Solution: Mendel studied seven pairs of contrasting traits in pea: stem height (tall/dwarf), flower colour, flower position, pod shape (inflated/constricted), pod colour (green/yellow), seed shape and seed colour (yellow/green). Trichome type was not among them. NCERT Reference: NCERT Class XII, Ch 4, p.54, lines 43-45: "Some of the contrasting traits selected were smooth or wrinkled seeds, yellow or green seeds, inflated (full) or constricted green or yellow pods and tall or dwarf plants (Figure 4.1, Table 4.1)."
