Biological Basis for Race

  • 84% of all variation is found within each racial group

  • 10% of variation is found among racial groups

  • More genetic variation is found within races than between them

The genetics of racial differences are quite surprising to most people. When scientists examine An organic compound made of amino acids arranged in a linear chain, joined together by peptide bonds between the carboxyl and amino groups of the adjacent amino acid residues.protein A common variation in the sequence of DNA among individuals of a species or race.polymorphisms (small genetic differences between people), the vast majority of differences (84%) are found within each racial group (between individuals of the same race). Only 10% of the variation is found between racial groups. Therefore, by far, there is more genetic variation within each race than between racial groups. In other words, the genetic differences that we cannot see visually are much more prevalent than the genetic differences we can see (racial differences).
