Since the Y chromosone is inherited directly father to son, does that mean that a guy has the same thingy as is father and grandfather? Ofcourse diet and health has some effect but is it baisically the same?
Mine is pretty similar to my dad's as far as I noticed (never got up too close but sometimes he'd walk around without pants on) which is pretty good for him considering he's alot shorter than me.
Anyways, the argument would have to pass a statistical test of environment vs. genetics, before you even start trying to locate it on any of the chromosomes.
No, that doesn't make much sense. There's no reason that all the possible penis-related genes would live on the Y chromosome. I think the Y chromosome is pretty small and not terribly important. But I suppose your penis might be like that too.

It is my understanding that the male and female reproductive organs follow similar paths in utero, with the presence of either testosterone or estrogen ultimately determining what forms they take. Thus in a sense the penis is what happens when a certain feature gets testosterone, the clitoris when it gets estrogen; and there are others that are the same. Meaning that the genes that have a role are just as likely found on the X, or any other chromosome.
