Obvious the size of the penis is a genetic subject, this is transmitted of parents to children, but that does not mean that in all the cases in where there is a family with the Father who has very long flaccid-penis his sons, they also have the flaccid-penises equal or much more long that the father.
The doctors say that there are certain characteristics of the human body that are transmitted generally by way of the Mother, like for example diseases like the Hemofilia. Some doctors think that if a mother had to her to father with the very long penis, this one mother is going to transmit the gens to produce long-penis to her sons, these children will have the possibility (probability) of developing very long penises when they are adult men.
The case of this one gentleman whom it publishes here, is a very rare case... He is a man of very long penis and his sons have the very long penis also then the Mother of these boys she must have had a father with the very long penis, of this one way, when she married with him, the boys of both developed very long penises due to the genetic load of both parents.
In the science of the Genetics the the MAN are the that determines the sex of the future son who is about to to be born, because the men have two classes of spermatozoon: Spermatozoa are of chromosome X (these produce daughters) and other spermatozoa are of chromosome and (these produce sons-boys).
When the spermatozoon is united definitively with the ovum of the woman (the ovum of her is always of chromosome X) settles down of clear form which is going to be the sex of drinks.
The women generally transmit certain characteristics that are Dominants, among them certain diseases and other characteristics antropomorphycs.
