the Lewontin–Krakauer test

The Lewontin–Krakauer test is a method used in genetics to examine how much genetic variation exists within a population compared to variation between different populations. By analyzing the genetic makeup of individuals, researchers can determine if differences between groups are significant. This helps scientists understand the role of genetic diversity in evolution, helping to identify whether populations are adapting to their environments or if they are genetically similar despite being in different locations. Essentially, it provides insights into population structure and the effects of natural selection.
