Assertion : Parthenogenesis does not play any role in organic evolution.
Reason : In parthenogenesis females develop into new organisms without fertilisation.

Options

A. If both assertion and reason are true and reason is the correct explanation of assertion.
B. If both assertion and reason are true but reason is not correct explanation of assertion.
C. If assertion is true but reason is false.

Explanation

Parthenogenesis is development of an egg (ovum) into a complete individual without fertillisation. Parthenogenesis occurs in its natural course in many invertebrates like insects, arachnids, some vertebrates and some birds (e.g., turkeys). Parthenogenesis eliminates variations in a population so it does not play any role in organic evolution.
