From his studies, Mendel derived certain basic laws of heredity: heritable factors do not mix but remain segregated; some factors are dominant, while others are recessive; each member of the parental generation transmits only half of its hereditary factors to each offspring; and different offspring of the same parents receive different sets of hereditary factors. This genetic code is passed on to the offsprings in both bisexual and asexual organisms. All living things inherit their physical and biological characteristics from their parents through heredity.
