What are your opinions of the genetic biodiversity of Mexicans?
Would relative isolation (at least in the past), coupled with rampant reproduction within a limited gene-pool (i.e. “in-breeding” to an extent), result in a “monoculture”?
Monocultures are only produced with very small initial gene pools and continued selection to eliminate heterozygosity in specific traits. This needs rigid control to limit cross breeding that is not likely in humans.
Evidence for normal genetic variations in national populations is available and has clearly been shown to be greater within most populations than between the various world populations.
An example of local adaptation in South America is the type of response to living at high altitude with low levels of oxygen. They have evolved to be able to carry a higher concentration of hemoglobin in the red blood cells. This is not the same adaptation the Tibetans evolved in response to their Himalayan environment.
When there are genetic markers found more commonly with a specific population they are designated the haplotype. The goal is to establish markers for use in creating a better ability to treat medical conditions since not all populations are the same
