It is due to polyembryony.
The occurrence of more than one embryos in a seed is called as POLYEMBRYONY.
In orange, the nucellar cells, synergid, or integument cells develop into a number of embryos of different sizes.
eg: Citrus.
- Sometimes the formation of more than one egg in an embryo sac can lead to polyembryony.
