As I understand, there may not have been different races if there had been a large population intermingling at the time. The same dominant traits would have expressed themselves in each subsequent generation.

For new traits to express themselves and become characteristic of different races, the survivors had to form many very small groups without contacts with each other for a prolonged period of time. Some of those traits may eventually disappear in the global village.

As an analogy, you could think of the evolution of the English language in the British Isles and in North America while populations were cut off from each others. Word and syntax usage grew different from place to place, a large variety of accents developed. The media and travel may have a leveling factor on those differences.

Are you familiar with the work of the fathers of genetics, Gregor Johann Mendel and Thomas Hunt Morgan?

"From his studies, Gregor Mendel derived certain basic laws of heredity: hereditary factors do not combine, but are passed intact; each member of the parental generation transmits only half of its hereditary factors to each offspring (with certain factors "dominant" over others); and different offspring of the same parents receive different sets of hereditary factors."

Answer to the chess board question - He asked for 2 grains of rice doubled for each square on the board. The Emperor was no mathematician and had never figured 2 to the power of 64. He grinned at the modest request and agreed... then quickly ran out of rice.
