Embryo sacs of some apomitic species appear normal but contain diploid cells. Suggest a suitable explanation for the condition.

Text Solution

Verified by Experts

Diploid embryo sacs are formed, if they develop from nucllear cells or diploid meagaspores. Diploid megaspore is formed from dipolid megaspore mother cell without undergoing meiosis. It may lead to the formation of embryos apomictally.
