The embryos formed as a result of polyembryony may or may not be genetically similar. In polyembryony, there may be more than one egg cell in an embryo sac or more than one embryo sac in an ovule. All the egg cells may get fertilised. The embryos may be developed directly from a diploid cell other than egg, e.g., nucellus, integuments or they may also develop from synergids and antipodal cells. If the polyembryony occurs due to the fertilisation of more than one egg, then the formed embryo will not be of same genetic constitution. But, if all the embryos develop directly from diploid cell, then they will have same genetic makeup.
