Excerpt from Human Heredity Perhaps so and perhaps not. Just at present we are not interested in crossing the white raceon a race of some other color, and if we should do so the law would prevent us from breeding brother and sister together to get the Mendelian segregation. Up to the present it has not been shown that we can get pure whites and pure blacks by breeding Mulattos together. Also, we are not particularly interested in inches in height, color of hair, or shape of physical organs, and these are the things with which the Mendelian theory deals. In a political campaign, the politi cal orator, in bringing forward the merits of his candidate, does not say: Vote for my man, he has brown eyes and curly hair, and is much superior to the other fellow, who has red hair and a pug nose. We are interested in improvements in mental power, physical strength and endurance, vitality, resistance to disease, and longevity. These are not unit characters at all, and consequently do not come under the Mendelian theory. Ou this point I will refer the reader to the New York Medical Journal for September 21, 1918.
