Which of the following is an example of adventive polyembryony?
Development of embryos from synergids and antipodal cells
Formation of extra embryos due to cleavage of growing embryo
Development of multiple embryos from a single egg
Development of multiple embryos from different egg cells
Adventive polyembryony is the formation of extra embryos through sporophytic budding. This can occur due to cleavage of growing embryo in gymnosperms.
Option 2 is the correct answer.
