Is It Genetic?

is penis size all genetic or is it something that is randome or something

[ThatCanadianGuy]

It isn't actually random... genetics and stuff obviously play a part in it (i.e. how big your dad is; but it still doesn't necessarily mean you will be of similar size). Its almost like a fingerprint; no two are exactly alike, though it has been accepted that the overall most common size is from 5 to 6 inches in length. How it looks is totally different to everyone.

[Atonement]

It is mostly based on genetics. Though, it could be genetics from either side of the family. You will probably be similar to some relative in your family. So to save you the lecture about dominant and recessive genes, I will just say that you will probably end up like SOME family member.

I would say it is 75% genetic and 25% random. It completely depends upon the family and the person I believe.

Id say it was 100% genetics, though as Atonement said, its all to do with the recessive and dominant alleles for the "penis-size" gene etc...if there is such a gene.
