Description EXPLORING HUMAN HEREDITY 15 P fc*#*"'! Figure 3 chance of being a carrier. She recently had a son who was born blind. This demonstrates that she is a carrier and that each son she bears stands an equal chance of being blind and each daughter an equal chance of being a carrier. In the other sex-linked trait, Choroideremia, we have another recessive gene on the same chromosome which has an entirely different effect. This gene causes a degeneration in the choroid layer back of the retina. It begins in early childhood and progresses until the individual is almost completely blind. A kindred having this trait was studied in our laboratory in cooperation with Dr. Dean Spear. The trait is inherited in the same manner as Microphthalmia. In this case, however, the doctor can identify the females who are carriers and can inform them at an early age that if they marry and have sons, the sons will have a fifty-fifty chance of being blind. On the other hand, their sisters who are not carriers can know that they drew the lucky or normal gene and therefore will never transmit the trait, nor will it occur in their descendants because of them. A search for methods by which carriers of recessive traits can be detected is of vital interest to the human geneticist. Dr. James V. Neel of Michigan has listed over thirty human traits for which the genetic carriers can be identified. Without doubt, even minute metabolic processes of the human body are gene-controlled. These can be studied only when muta-
