Do all or any of you believe the large penis comes from the dad's side of the family, mom's side or both? Have any guys at a talk from their dad about the family jewels?
If you're a man, your genetic makeup comes from your mother (X - passed from Mother to daughter) and your father (Y - passed from Father to son).
Now if you want to figure out what family line your penis size comes from, you need to know that your fathers X chromosome, which came from his mother, was not passed to you. A male sperm only contains Y information which technically means you have no X genetic material from your fathers mothers side or your fathers, fathers, mothers side who he got his X from. This is because your Y genetic information has been passed down through the generations only from father to son, going all the way up the family tree. As a result, it is the only DNA that would affect if you have a large penis on the fathers side. If your father, grandfather, great grandfather etc were hung, then the likelihood that that was passed to you is quite good.
Likewise, you have no genetic information from your mothers father. Only her mothers X chromosome was passed to you, not the X from her father. So if men in your mothers mothers family has a history of large penis's, then it can be passed that way.
Together your mothers X and your fathers Y will create a unique person who has DNA from both parents and this mix will ultimately determine your penis size.
If both your fathers fathers side and your mothers mothers side have a history of having large penises, you're most probably 10" and thickly hung. :biggrin1:
