In case of polyembryony, an embryo A develops from the synergids and the embryo B develops from the nucellus. State the ploidy of embryo A and B.

Explanation

To determine the ploidy of embryo A and embryo B in the case of polyembryony, we can follow these steps:

### Step-by-Step Solution:

1. **Define Polyembryony**:
- Polyembryony is the phenomenon where multiple embryos develop from a single fertilized ovum or seed. This means that from one fertilized ovum, more than one embryo can form.
