The spectre of inbreeding in the early investigation of heredity.
Inbreeding introduced by R. Bakewell (1725-1795) in England for creating new animal races, was opposed by animal breeders on the Continent on religious grounds, and was soon introduced in sheep breeding for wool production in Moravia. In 1790-1840 the protagonists repeatedly rejected 'the spectre of inbreeding' and included consanguineous matching in scientific breeding. In 1836 they even formulated the research question of heredity and next year proposed the inductive method for its investigation. The achievements of sheep breeders instigated German breeders to reject the dogma of the constancy of race and to elaborate the theory of individual potency. Treating heredity as the force under the influence of environment they could not solve the enigma. The question formulated in 1836 was explained in 1865 by Gregor Mendel. His theory was not perceived by animal breeders as well as by biologists up to the end of the century.
