If my father is bald and I'm 26 years old and not bald, is there a possibility that I'm gonna be bald?

Not necessarily. If you're concerned, I suggest seeing a hair loss expert to evaluate and go over your condition and provide you information about your best treatment options. There are great non-invasive options like PRP/progesterone and/or hair transplantation. See an expert. Best, Dr. Emer

While the primary baldness gene is on the X chromosome, which men get only from their mothers, other factors are also in play. The hereditary factor is slightly more dominant on the woman's side, but research suggests that men who have a bald father are more likely to develop male pattern baldness than those who don't.

If I had a crystal ball, my job would be much easier. The genetics of hair loss are not as straight forward as the color of your eyes. It is safe to say if there are mostly bald men in your family on both sides, chances are you will have some degree of baldness.  If fewer members of your family are bald then your chance is less but it is never zero. Also, the onset of baldness can vary as well as the severity throughout generations. Male pattern hair loss occurs from approximately age 18-65 years old. After that, there are mostly age related changes that  cause thinning. Only time will tell what your pattern will be.
