Question about genetics and race

[Travis Retriever]

Does the bottom text ("cascading gene expression" 's definition, etc) refute the upper text (something I've seen Shane point out)?

short answer: yes, Shane would be right.

EDIT: I got what you were saying. I've gone ahead and fixed the sentence, to make it clear

I should probably clarify:  Shane would put out that Gene variations between individuals is greater than between races.
I am asking if "cascading gene expression" refutes the above.

So if Shane is right, the answer would be "no".

don't worry, I got what you're saying. I meant to say "yes, Shane would be right". I'm agreeing with his opinion. differences in "races" is really superficial at best; we're basically clones of each other. (in short, races aren't physically real: they're a social construct).

EDIT: the lower half would only work if we had more genetic diversity, and the populations were isolated for a very long time--to be sure. as it is, a troop of Chimps has more diversity then all 7 billion of us. also, we aren't that isolated from each other (there's large admixing between the many populations), and we were all in Africa as recently as 60,000 years ago, with the population being very small.

in short, I would agree with the assessment that there are more differences between individuals than "races".

EDIT2: wait, gene expression, not gene flow? XD

meh, either way, the lower part doesn't refute the upper part.

Actually, I believe what I said was gene variations between races is NO GREATER THAN variations between UNRELATED individuals. I wouldn't expect it to necessarily be greater; the way you worded it made it sound like I don't think they could be equal.

I am asking if "cascading gene expression" refutes the above.

Gene expression--cascading or otherwise--has NOTHING WHATSOEVER to do with it. Gene expression deals with how the genotype leads to particular phenotypes, in other words, what genes get turned on and off where and when, and how the organism develops as a result.

Another interesting detail about the alleged differences between alleged races and different people:

There are models (based on the data being gathered to quantify the actual genetic diversity of our species) that indicate if you go back 5000 years, 80% of the population is ancestral to EVERYONE alive today (and the other 20% are ancestral to nobody alive today, their lines having died out).   All of this is just from normal gene flow between adjacent populations.

@Shane:  Sorry for misquoting you then.  My bad.
@Ibrahim90, Shane, evensgrey:  Thanks for the replies.
