blending inheritancea pre-20th century theory that the male and female GAMETES each contained essences from the various parts of the parental body, which were mixed at fertilization to produce offspring showing some features of both parents. The theory was backed up by results from crosses involving quantitative characters (see POLYGENIC INHERITANCE in which there was an apparent mixing of PHENOTYPES due to segregation of polygenes.
