Answer 1

To determine the probability of the offspring being purple based on the Punnett Square provided, let's analyze the results:

From the Punnett Square you showed:

```
P P
__________
p | Pp | Pp |
__________
p | Pp | Pp |
```

- All the offspring (4 out of 4) are Pp (heterozygous), which means they all have at least one dominant purple allele (P).

Since purple (P) is dominant over white (p), every offspring will display the purple phenotype.

Thus, the probability of an offspring being purple is:

**100%**

So the correct response is **100%**.
