If my dad have a big one.?

If a dad has a big penis does that mean his sons will?
Most likely,
Yes. Its genetically connected. But why did you look at your father penis anyway? You have no business looking at his penis, and he cant look at your area any. generally yes
but if you had the penis size setting for his parents and your mother's parents and grandparents i could work out the math for you
It is interesting some of the research on penis size. Currently, the dominant gene for penis size is found on the mother's chromosome. What does this mean? If your father is economically endowed and your mother's father is average, you will be more likely to be average or just above average. If your father is packing and your grandfather on your mother's side passed on the "big" gene to your mother by her X chromosome, afterwards when you are born you are likely to be one of us "lucky" guys.

The interesting topics I have see on other forums about penis size and family is the shock factor. There are stories of father and sons later in enthusiasm (when the son is in his 20s) showering at the gym with their father (communal showers) and the son realize that he is larger than his father, or the flip side that the son is average and the father is well-endowed.

Just accept the penis you have, and remember that respectively man is not measured by the size of his schlong.
it depends on ur race.if ur asian ur screwed. Unless you're breeding porno stars, does it matter?? ha, that's funny. You grasp what you get, gotta luv it
it could be. just remember, the gene pool is full of genes, so it's also possible that some gene will make it within the mix that gives you a teeny weeny. I've seen brothers who be miles apart in size.
you sick bastard. what you and your dad do in the privacy of your basement contained by front of the video camera is your buisness. And no yours will be as small as his is big. it could be. just remember, the gene pool is full of genes, so it's also possible that some gene will make it within the mix that gives you a teeny weeny. I've seen brothers who be miles apart in size.
generally yes

Answers:    Genetically yes.though it depends on factor such as your granparents etc. Traits not seen in parents can crop up within children. for example a friend of mine has parents and grand parents who adjectives have brown eyes and he has blue ones.

It depends on diverse different things. But strictly speaking you have a bigger chance of have a larger penis than you are of having a smaller one.

normally yes, the genetic factor approaching father like son lol...
