Assignment:

Explain the difference between the concept of the traditional use of the word "genetic mutation" and the more contemporary term "genetic variant". Explain the concepts of 1) harmful mutations and purifying selection, 2) of neutral mutations and 3) variants that are retained via positive (or Darwinian) selection. Explain how a positive variant may influence local alleles (on the same chromosome very close to the new positive variant) by selective sweep of hitchhiker alleles.
