The eminent geneticist Gedda and his collaborators studied a series of 44 war mulattoes (hybrids) from 8 to 12 years of age—34 boys and 12 girls, 35 offsprings of mating between Negro men and white women, 6 offsprings of a mixed group (Polynesian-Italian, American Indian-Italian) during the last war in Italy.
The study consists in measurements, colors of skin, color and types of hair, shape of nose, lips, x-rays of bones, encephalograms, basal metabolism, hematograms, inheritance patterns, rate of growth, and psychometric tests.
Mulattoes are subgrouped as follows: border mulattoes, slave mulattoes, colonial mulattoes, war mulattoes, and melting pot mulattoes—this last subgroup due to the modern way of international connections.
The cases are described in detail. The colors are according to the Gates chromatic scale. The printing and the color illustrations are excellent. It should be of interest to the dermatologist.
