• Properties of Restriction Maps:
• Statement (A) is incorrect: A restriction map is a physical map showing absolute base-pair distances between endonuclease cleavage sites, not a linkage recombination map.
• Statement (B) is correct: Points on a restriction map correspond directly to specific restriction recognition sequences.
• Statement (D) is correct: Physical maps are constructed by comparing fragment sizes generated by single and double restriction enzyme digestions separated on agarose gel electrophoresis.
• Conclusion: Statements (B) and (D) only are correct. (Correct answer: Option 2)

• Template Strand of DNA:
• The specific single strand of the double-stranded DNA duplex that RNA polymerase reads ($3' \rightarrow 5'$) to synthesize a complementary mRNA molecule ($5' \rightarrow 3'$).
• Also termed the antisense strand or non-coding strand.
• The complementary non-template strand is termed the coding or sense strand. (Correct answer: Option 1)

• Statement (I) is Incorrect: In maize (Zea mays), Stock 6 is a classical maternal (gynogenetic) haploid inducer line developed by Coe (1959); when used as a male pollinator on diploid females, it induces maternal haploid progeny at a frequency of approximately $2-3\%$, not paternal haploidy.
• Statement (II) is Incorrect: Paternal haploid induction (androgenesis) in maize is mediated by the _indeterminate gametophyte_ (_ig1_) mutation (discovered by Kermicle, 1969), which affects female embryo sac development; Stock 6 gynogenesis is governed by mutations in the pollen-specific phospholipase gene qhir1 / MTL / NLD / ZmPLA1, not the ig1 gene.
• Conclusion: Both Statement (I) and Statement (II) are incorrect (Option 2).

Correct option: (2) Both Statement (I) and Statement (Il) are incorrect
