It was somewhat of a hit or miss process since the actual mechanisms governing inheritance were unknown. Knowledge of these genetic mechanisms finally came as a result of careful laboratory breeding experiments carried out over the last century and a half. By the 1890's, the invention of better microscopes allowed biologists to discover the basic facts of cell division and sexual reproduction.
