It has been widely believed that Gregor Mendel's experiments with peas (genus Pisum) were designed to discover the basic principles of heredity (genetics). Those more familiar with the history of genetics know that his work with peas sought to explain the laws governing the origin and development of hybrids (Hartl and Orel 1992, p. 245; Monaghan and Corcos 1985, p. 49–50; Stern and Sherwood 1966, p. 2). His subsequent work with hawkweeds (genus Hieracium) was an attempt to find an explanation for the apparent constancy of some hybrid forms in this and other species (Orel 1984, p. 63). One of his main motives was to see if hybrids between different varieties of a species or between different species could breed true, that is, hybrids produce only more hybrids. In those days, the difference between varieties and species was not always well defined.
