Penis Size not Hereditary?

I was searching the forum for answers on this question. It seems to me that offspring do not inherit penis sizes, or rather they do not inherit it equally at least. We could only really know how dependent penis size is on parental genetics by measuring the father’s size and perhaps the mother’s side’s brothers. But I noted this post in another thread Small/Big Penis Genetic?

I would guess that all physical characteristics are hereditary. And, obviously, diet and exercise have a lot to do with how those physical characteristics manifest themselves.

In my case, the men in my family tend to have wide shoulders, narrow waists, broad hips, and slender legs: of all of the men in my family I alone posess mounds of muscle on this framework as the results of exercise.

When it comes to the expression of physical characteristics, nature and nurture are not mutually exclusive.

I took multivitamins everyday since I was 8. My little brother did not. I wonder if that helped or hurt my size compared to his. Do you guys think its mandatory that the first brother will always have the bigger penis? I ended up with less height sort of. I have a larger head but shorter neck. I am naturally more muscular and even more so due to bodybuilding. My shoulders are equal in height as his. I have smaller hands. and 1/2 smaller shoe size. But as we all know theres no real correlation with these measurements.

That topic always will be a myth, I think so.

I think there are some big chances that you look like your brother, but there’s also a chance that you don’t look like him at all. We couldn’t compare you with your brother because you have a slightly other DNA structure then his (fenotypically, as in what you look like).

Identical twins however have an identical fenotype so we could compare them many years afterwards. For example, if one twin has an office job and the other one is a construction worker we all know the construction worker would be more muscular, have rough hands,…

So maybe we could find out about these natural elements that have an effect on penis size betweens identical twins. I know there are a lot of studies on the body but I haven’t found one yet as a subject to penis size on the net. But maybe someone has?

Twins would be a good control group to measure if any environmental stimuli affects penis size. Good idea :) maybe its on the net somewhere. Any twins here on Thunder’s?!

I look different from my brother in so many ways. Which could mean that the sizes are also quite different, there is ONE feature we share for sure but I don’t want to talk about that yet. It’s just important to know that we are linked in at least one obvious way genetically.

The thing here is that if we have kids they will inherit our PrePE size or PostPE.. :P
