Answer 1

To determine the frequency of the blood group O in the provided data, we will count the occurrences of the letter 'O' in the sequence.

The given blood group sequence is:
OABOOOOOABOOOOBOBOAAAOAABABABAAAAOAOOAAOOAOOOOAAAAAAB

Now, let's count the number of 'O's in the sequence:
- OABOOOOOABOOOOBOBOAAAOAABABABAAAAOAOOAAOOAOOOOAAAAAAB

Counting the 'O's, we find that there are 22 occurrences of the letter 'O'.

Therefore, the frequency of the blood group O is:
**22**

The correct answer is:
**4) 22**
