Question
What is polyembryony and how can it be commercially exploited?

Solution
The occurrence of more than one embryo in a seed is called polyembryony.
- Embryos developed through polyembryony are found virus-free.
- The seedlings formed from nuclear tissue in citrus are found on better clones for orchards.
- Because nucellar adventive polyembryony produces genetically homogenous parental type seedlings, it is very important in horticulture.
- Plantlets derived from these embryos are free of illness. These embryos can be separated and cultured to make clones.
