  • All human races have the same number of chromosomes (46) and banding pattern. All human races can interbreed and produce fertile offsprings, so all belong to the same species.
  • On comparing the amount of DNA in human diploid cells and that of gorilla chimpanzee, and great apes (2N = 48), it is observed that the DNA contents in them are similar proving common ancestry of all of them.
  • On staining the autosomal chromosome number 3 and 6 of man and chimpanzee with a specific dye, it was found that bending pattern of chromosomes (chromosome number 3 and 6) of man and chimpanzee is quite similar.
