In DNA, the base pairing rules established by Chargaff indicate that the amount of Adenine (A) is equal to the amount of Thymine (T), and the amount of Cytosine (C) is equal to the amount of Guanine (G).

From the information provided:
- A = 22%
- G = 28%

Since A = T, you can conclude that Thymine (T) must also equal 22%.

Therefore, the expected percentage of Thymine (T) in the sample is **22%**.

The correct answer is **22%**.
