Question

In case of polleyembryony if embryo develops from the synergids and anther from the nucellus which is haploid and which is diploid

Answer 1

Synergid is a part of egg apparatus of haploid embryo sac, and thus is haploid in nature. Nucellus, on the other hand, is diploid sporophytic tissue. If, by the means of polyembryony (formation of more than one embryos in an ovule) and apomixis (omission of fertilization step), two embryos are formed that is one from synergid and the other from nucellus, then the synergid embryo will be haploid and the nucellar embryo will be diploid.
