Question

In case of polyembryony an embryo A develops from the synergids and the embryo B develops from the nucellus. State the ploidy of embryo A and B

Answer 1

The synergids are haploid in nature and the nucellus is located within the integumentary region and has abundant reserve food materials. It is diploid in nature. So, embryo A that develops from the synergids will have a ploidy of n and embryo B that develops from the nucellus will have a ploidy of 2n.
