  • An organism is reproducing by asexual method of reproduction. The organism splits into two identical daughter cells. This happens when the cellular organism reaches to its maximum size of growth and then the nucleus of the organism elongates and divides into two parts. After that the cytoplasm also divides into two parts along with cell. Which of these statement is not a feature of asexual reproduction ? a) No meiosis occurs b) New individuals are genetically identical to the parents. c) Offsprings are clones of parents. d) Two individuals of different sexes involved.

    B
