Solution & Explanation
Answer: (A) Both Statement I and Statement II are correct Solution: Statement I is correct: Mendel studied seven pairs of contrasting traits in pea plants and proposed the laws of inheritance. Statement II is also correct: the seven characters were stem height, flower colour, flower position, pod shape, pod colour, seed shape and seed colour (as listed in Table 4.1). Both statements are therefore correct. NCERT Reference: NCERT Class XII, Ch 4, p.55, lines 035-060: "Table 4.1: Contrasting Traits Studied by Mendel in Pea ... Stem height Tall/dwarf ... Flower colour Violet/white ... Flower position Axial/terminal ... Pod shape Inflated/constricted ... Pod colour Green/yellow ... Seed shape Round/wrinkled ... Seed colour Yellow/green"
