Thank you for your answer, I understand that I am scrupulous about this question, forgive me that there are still questions.You can do that, however I don't know if it would be a mistake or not to list yourself as the father. You can verify from the IO when you go for the interview if you should have listed yourself or the biological father (since you did not formally adopt her) as the father. If you wrongly listed yourself, the IO will make the needed correction at that point.
