Description 28 TWENTIETH ANNUAL REYNOLDS LECTURE Another factor was the total number of leucocytes or white blood cells. There was a definite correlation between the number of leucocytes and resistance to the disease. Thus the number of white blood cells for a particular strain was gene-determined, and this in turn was one factor in determining its resistance to the disease. Twins In some traits there are insufficient numbers of affected individuals in any one kindred to make it possible to determine the nature of inheritance by use of the pedigree method. In these cases another approach has to be made. One method used is the twin method. Kallmann has used this method to study schizophrenia and susceptibility to tuberculosis. In both studies he has found that if one member of a pair of identical twins shows the defect, the other is much more apt to show the same trait than are ordinary sibs or even like-sexed members of fraternal twins. While this type of study suggests the influence of heredity, it of course does not give us the pattern of inheritance involved. Where proper safeguards are used, however, it is a very useful tool in human genetic studies. Human Cancer One of the most baffling problems of medicine is the cause and cure of human cancer. In 1944 cancer ranked second in causes of death in Utah. The fact that in the past cancer of different kinds has been found in more than one member of the same family has raised the question of whether or not it is hereditary. Because of the complexities of the disease, every known method of approach has been used to determine the part heredity plays in its production. The best work which has been done on the genetics of cancer has been done with mice. They have the advantage over humans in that they can be inbred and crossed at will. By inbreeding, it has been possible to establish strains of mice highly susceptible or highly resistant to many of the common types of cancer. It can probably be done for all types. In no case has susceptibility been shown to be due to a single gene, but rather to multiple genes. So far, work done with human beings suggests the same conclusion. In our laboratory, pedigree and statistical studies have been employed in an effort to throw light on this subject. Statistical studies involving cancer of the breast, the stomach, and the large bowel
