In many Citrus and Mango varieties, multiple embryos may develop in a single seed because:
ANucellar cells surrounding the embryo sac divide and develop into embryos inside the embryo sac
BMany sperms fertilise many eggs
CThe zygote divides repeatedly into many embryos
DThe endosperm fragments
Answer & Solution
Correct answer: A. Nucellar cells surrounding the embryo sac divide and develop into embryos inside the embryo sac
**Adventive (nucellar) polyembryony**: nucellar cells protrude into the embryo sac and develop into embryos. Common in Citrus and Mango — each seed may contain many embryos of different sizes, mostly clones of the mother plant.
