Professor PC Thomas Classes · Answer

(a) : Presence of more than one embryo inside the seed is called polyembryony. It is more common in gymnosperms than angiosperms. In angiosperms, it is generally present as an unusual feature in few cases like Citrus, mango, etc.\ In Citrus many embryos are formed from the structures outside the embryo (like nucellus). This is commonly called adventive polyembryony.\ In Citrus upto 10 nucellar embryos are formed.
