I only gave you one bit of information, so don’t extrapolate from it yet. 😉
Explanation:
There are four possible values to every position (SNP). This is the base-four logic of the genome. Each position can carry a bit.
0: adenine (A), 1: guanine (G), 2: cytosine (C), and 3: thymine (T).
The SNP is first of the opportunities for mutation in the chain of opportunities for mutation. I’m not going to list them all here for now.
And SNPs are the most common type of genetic variation among people.
SNPs occur at a frequency of about 1 in every 300 nucleotides. This means that in a human genome of about 3 billion base pairs, you could expect to find approximately 10 million SNPs.
That means we have 10 million variables to compare between people and groups.
When we measure SNPs we measure correlations between populations and expressed traits. So X population has his mutation, and Y population has that mutation etc.
So for example we know which genes cause skin color (just a few). But most traits are more complex than that.
Intelligence appears to include thousands of variations. Which could mean a few things – not all of which are intuitive. ie: is intelligence that forgiving? Is it that unprotected? is it available through many permutations?
In the chart I posted the data shows a high correlation between a group’s SNP “pattern’, and their resulting IQ test scores. This is pretty convincing evidence and should end the IQ difference question.
