Explanation / Answer

11. An examle of postmating reproductive isolation is gamete incompatibility in what ch sperm transfer takes place but egg is not fertilised. Rest of the. Options mechanical incompatibility, behavioral isolation and habitat isolation are example of premating isolation.

Hence option B is correct.

12. Spores produced in meisis are haploid and unicellular and are produced in sporangium. Thus it is false that meiosis produce diploid spores.

13. Samen is s the male part of flower and it is also called androecium. Thus option B stamen is correct.

14. Mechanical incompatibility s example of premating reproductive isolation mechanism. It is a mechansm in which ogansm tries to copulate but transfer of sperm does not take place. Othee options like gamete incompatibility and hybrid inviability are examples of post mating isolation mechanism. Hence option A is correct.
