(these are often in low concentrations and may be below the threshold of detection in some instances) (4) hybrid-specific substances A few substances of type 4 were regularly present in hybrid types but not in the parental types. It was not possible in the original work to determine whether the "hybrid substances" were de novo products of the hybrid's gene combinations or accumulations of substances normally produced in small amounts in one or both parents (compare Schwarze, p. 315). Subsequently, it has been found that all four of the so-called "hybrid substances" are actually typically produced by.
