How Tall Are You?

I'll show you the mother of all tall people. My friend Trevor is exactly 7'0 and his brother is 7'1 and kid you not, when I stand next to him (me being a mere 5'4) I only come up to about his elbow. It's awesome :D

Someone 6 2 and higher... the mental image in my head is pretty much me and a a human looking skyscraper.

He is extremely tall. It's funny because people ask him all the time if he plays sports but unfortunately his legs are so long he looks like a gangly dinosaur when he runs.

LOL this guy I went to high school with was 7'6" I kid you NOT! His sister was 7'2". First time in my life I ever felt like a midget. My face came up to just a wee bit above his elbow hahaha. He plays in the NBA now.

YES!! that must be it! O_O. So funny, the elder siblings are freakishly tall (6'8" and up) while the younger ones and the parents are all average height. ::p::eek:

It is insane that someone can grow to that length! I call Trevor the Green giant and tell him his arms are tree branches ::p: The only time I've heard of people reaching those heights is when they have an over active gland. But I don't think that's his problem?

Hmm..When he joined the national basketball team they did a segment about him in the news. Something was mentioned about genetic conditions and that could be the cause but I just think it's a case of recessive height genes.

Why recessive? Are you suggesting that there are polypeptides/proteins that without them we'll all be this tall? And anyway, height is polygenic.

I think most people who grow up to be extremely tall have a tumour in their pituitary gland, which overproduces growth hormone. I don't know about any genetic conditions; all of the famous tall people I've heard of had this growth in their pituitary gland.

I say recessive because, at least in his immediate family, I have not seen anyone else but him and his sister exhibit such a tremendous height. His younger siblings are all average height (the tallest one being about 5'6"-5'7") and his parents/other immediate relatives are either short or average height themselves. If it is the pituitary growth you mentioned it could be a genetic hormonal defect that was carried on by both parents from distant ancestors and neither knew about it. When it comes to genetics it's pretty much hit or miss.

That's not what I was suggesting at all but it's not an impossible theory either..like you said height is polygenic. We are not carrying just our parents' DNA but our ancestors as well. We don't know how tall they might've been. We carry a LOT of genetic information that in most cases is randomly selected and must be juggled/controlled. When genes recombine there are several proteins with a strict code of instructions whose job is to regulate all hormonal processes through life, including height. If a mutation were to occur on the genetic code or the protein responsible for height regulation was absent it's not outrageous to say that, depending on the error, less or more growth hormone would be produced/released resulting in either extreme tallness or stunted growth. Remember we are not born with a set height. Even external factors such as exercise and diet can alter height to a very small degree in some cases.

There are genetic conditions that cause short stature and if I'm not mistaken that also cause giantism. Tumors can also be genetically influenced. Anyhow, I don't remember much of the segment as it was aired some time ago but I think that the cause was in fact the overgrowth gland tumor.

All good points that I accept, could be correct. You could have also added the possibility that a recessive gene might induce the transcription mechanism of a completely different gene instead of the one that it was supposed to go for, and that this active new active gene will in some way or another increase height. This is all theoretical, though

BTW, I really didn't mean to be confrontational or anything. Just in case that's how I came across...
