In diseases, on the other hand, which affect a large percentage of the population, as tuberculosis, or cancer, for instance, the frequency of the occurrence in parents of an affected individual is no indication of the influence of heredity. The same disease may be found just as frequently in the parentage of an individual not affected with the disease. Simple enumeration of the cases of the disease among parents and offspring cannot indicate the influence of inheritance, but the aid of certain laws of regularity in the recurrence must be sought. The Mendelian laws of heredity present such regularity and seem to offer the most promising basis for the study of the influence of heredity in disease. It may be well to present the main outlines of the Mendelian theories before the actual methods employed in the present investigation are stated. Reprinted from the Zeitschrifl fiir Krebsforschung, n Bd. The fundamental laws of the science of modern genetics were discovered by Gregor Mendel in 1865, but they passed unnoticed until they were rediscovered simultaneously by De Vries, Correns, and Tschermack, in 1900. Mendel subjected to experimental analysis the commonly known fact that an offspring may resemble in its different traits of character one or the other of its parents. He argued that a multicellular organism develops, not from a single germ-cell, or gamete, as it is called in genetics, but from a zygote; by which is meant the resultant of the union between the maternal and paternal gametes. In order to learn the fate of parental characteristics in the offspring, certain simple features have to be selected in each parent and studied in the following generations. These simple features are called unit-characters, and in order to be better able ...
