Which of the following is INCORRECT for recurrent apomixis?

Options

  1. AEmbryo sac generally develops from an archesporial cell
  2. BEmbryo sac develops from other part of the nucellus
  3. CEmbryo sac develops from megaspore mother cell.
  4. DEmbryo develops from reduced egg cell

Correct answer

D. Embryo develops from reduced egg cell

Step-by-step solution

In recurrent apomixis, both the egg cell and the embryo are diploid because the embryo sac develops without meiosis. This can occur either from the megaspore mother cell (diplospory) or from any other cell of the nucellus (apospory). Since meiosis does not take place, the egg cell is unreduced (diploid). The development of an embryo from a reduced (haploid) egg cell without fertilization is known as non-recurrent apomixis (haploid parthenogenesis). Therefore, the statement that the embryo develops from a reduced eg
