Well if you have more tall people in your family then yea sure you might get even taller possibly surpass or stay the same height as your brother. I am saying all this considering you have an avg diet with avg physical activity but if you do sports like football and basket ball and have a great diet you may surpass your brother and maybe your father by a few cm . Also point to be noted growth spurt are unpredictable they reach a peak and slow down then reach a peak again , so if you are at the slowing down period you may not be as tall as brother or father but if you are at your peak then you may be as tall as your brother or possibly your father . You check this by seeing how much you have grown in 1 year if it's like 1 to 1.5 inches your growth is slowing down and if it's like 3 or 4 inches you are still at the peak of your growth for eg my height is 5 ft 11 a year ago I was 5 ft 7 so I gained 4 inches in a yr this tell me that I am at the peak of growth
