This paper is one of the fruits of an expedition to Eastern Cuba in January and February, 1952. The names of many individuals who aided these investigations in various ways will be mentioned later in the course of this work. Authorities of the Universided de Oriente in Santiago de Cuba procured the indispensable cooperation of all the families in Santiago whose data are recorded here. I wish to thank all the individuals concerned for the friendly way in which they cooperated, permitting records and photographs, as well as blood specimens to be taken, and for the interest they showed in this work. I was also able to make a study of Indians and their descendants in Eastern Cuba, which has been published elsewhere (Gates 1954a).

Introduction

Many records of the results of various racial crosses have been made, some of which will be referred to later. These studies have been partly on the inheritance of characters which are from one point of view qualitative, such as skin color, eye-folds and hair characters, but the emphasis has frequently been on purely quantitative characters, based on anthropometric measurements. These results have previously been generally treated as a matter of population statistics, not based on individual pedigrees.

Trevor (1953) has carefully analyzed the inheritance results to be derived from the investigations of metrical characters in racial crossing. Selecting the nine investigations which are sufficiently extensive to yield results having statistical significance, he finds that in some cases the hybrid series are more variable, in others less variable than the populations which are chosen as more or less representative of the original parents. This mixed result is not surprising when one recognizes that the populations chosen as “parental” must differ more or less markedly from the actual ancestors of the hybrid populations. In fact, much difficulty was encountered in selecting populations as presumptively equivalent to the parents of the various crosses, since they had to be groups in which sufficient anthropometric measurements had been made. But notwithstanding the many…
