A. When a seed of an orange is squeezed, instead one, many embryos are observed in it. This happens due to the phenomenon called polyembryony. Polyembryony may arise due to the development of embryos from synergies or from antipodal. Some embryos can also be developing from sporophyte cells of ovule such as nucellus or integument.
B. The embryos develop as a result of polyembryony are genetically similar. The embryos developing from gametophytic tissues such as synergies and antipodal are similar to each other, but not to their parents. Similarly, the embryos that are formed from sporophyte tissues are usually similar to each other as well as their parents.
