In October of 1939 I was asked to come to Broadlawn General Hospital in Des Moines to see a child, Pedro, that had recently been born of Mulatto parents. A former student of mine, Dr. Kirby Shiffler, who at that time was a resident interne at the hospital, had become interested in the child because of the unusual number of recessive traits which were obviously present in his phenotypic makeup. With the aid of several of the hospital staff and many different relatives of the child as well as his parents, the information in the accompanying chart was obtained.
