Genetic Diversity

Slide 27 of 109

Scientists examine human genetic diversity using Of or referring to the mitochondria, the organelles that generate energy for the cell.mitochondrial Deoxyribonucleic acid: the chemical inside the nucleus of a cell that carries the genetic instructions for making living organisms.DNA, Y chromosomal Deoxyribonucleic acid: the chemical inside the nucleus of a cell that carries the genetic instructions for making living organisms.DNA, The association of genes and/or markers that lie near each other on a chromosome that tend to be inherited together.linkage disequilibrium, and Repetitive stretches of short sequences of DNA used as genetic markers to track inheritance in families.Y microsatellites. The results of the studies show that modern humans arose 40-100 thousand years ago. The most genetically diverse populations are from Africa, suggesting an origin at or near that locale. The limited genetic diversity suggests that humans originated from a small population of individuals that expanded recently.
