Is my hairline receding and if so by how much?

[Receeder69]

So I'm 20 years old and have recently noticed after a haircut that my hairline might be receding. My father started balding in his 30's, he's in his 50's now and still has some hair left but a massive bald pitch in the middle of his head. So I wonder if there's something genetic there. I've attached some photos so you can all let me know what you think.

I can still grow my hair out quite long if that matters, down to the bottom of my neck and past my eyes.
