Final answer:
In Yuzu seeds, the plants growing out of the same seed are more genetically similar than the plants growing out of different seeds.
Step-by-step explanation:
In polyembryony observed in Yuzu seeds, the plants growing out of the same seed are more genetically similar than the plants growing out of different seeds. Polyembryony is a phenomenon where multiple embryos develop from a single fertilized egg. In Yuzu seeds, multiple plants can grow from a single seed due to polyembryony, which means that they have the same genetic material inherited from the parent plant. This makes them more closely related to each other.
