Answer

  1. Citrus

Explanation:

Polyembryony is the occurrence of more than one embryo in a single seed.

In adventive polyembryony, there is the formation of extra embryos due to sporophytic budding.

One or more sporophytic cells, either nucellus or integuments undergo stages of embryogeny and eventually develop into mature embryos.

This kind of polyembryony is found in citrus fruits.
