Genetics and Penis size

[Big O]

Does parents or grandparents size have anything to do with lenient size because me and my brother hes 18 are both have big penises but our dad doesn't seem to. Could it have anything to do with grandparents?:D

Its a possibility.

It could be, or it could be from your mothers? Is penis size in the y-chromosome? If it is that would mean that women don't have penis DNA, so it would have to be from your fathers y-chromosome, but his genes might have expressed a smaller penis whereas yours and your grandparents expressed a larger penis? Idk.

Maybe, Although I don't know. I don't have any brothers , I don't have a father and the only guy I know is my grandfather and he is 70. He isn't my biological one so Idk .

I heard that you get your size from your Mother's Father. Mine is nothing like my Dad's (soft), so I think it's true.
