Abstract
THE state of genetical knowledge in 1910 can be learnt from Bateson's “Mendel's Principles of Heredity”, of which the first two editions were published in 1909 and 1913. The principles which Mendel had shown to hold for seven contrasted pairs of characters in Pisum had been extended to a very large number of characters in many plant and animal species, including man. The main additions to these principles were the pure line, multiple allelomorphism, partial linkage between genes, epistasy, and one of the four types of sex linkage now known. The latter discovery, along with cytological work, had made the genetics of sex determination fairly clear. At least one case of extranuclear inheritance had been recorded.
