"Oh ? Then what do you take this to mean ? : http : //www.accessmylibrary.com/comsi ... d=0286-6387354 `` researchers no longer believe that races are distinct biological categories created by differences in the genes that people inherit from their parents. `` http : //academic.udayton.edu/race/01race/race.htm There are no genetic characteristics possessed by all Blacks but not by non- Blacks ; similarly , there is no gene or cluster of genes common to all Whites but not to non-Whites . One 's race is not determined by a single gene or gene cluster , as is , for example , sickle cell anemia . Nor are races marked by important differences in gene frequencies , the rates of appearance of certain gene types . The data compiled by various scientists demonstrates , contrary to popular opinion , that intra-group differences exceed inter-group differences . That is , greater genetic variation exists within the populations typically labeled Black and White than between these populations . This finding refutes the supposition that racial divisions reflect fundamental genetic differences . Along the way , various minds tried to fashion practical human typologies along the following physical axes : skin color , hair texture , facial angle , jaw size , cranial capacity , brain mass , frontal lobe mass , brain surface fissures and convolutions , and even body lice . As one scholar notes , `` [ t ] he nineteenth century was a period of exhaustive and -- as it turned out -- futile search for criteria to define and describe race differences . '' . . . Attempts to define racial categories by physical attributes ultimately failed . By 1871 , some leading intellectuals had recognized that even using the word `` race `` `` was virtually a confession of ignorance or evil intent. `` The genetic studies of the last few decades have only added more nails to the coffin of biological race . Evidence shows that those features usually coded to race , for example , stature , skin color , hair texture , and facial structure , do not correlate strongly with genetic variation"
