Are there anthropometric differences between the offspring of endogamous and exogamous matings?

Measurements of 133 adult offspring of exogamous matings and of 347 adult offspring of endogamous matings in a Mexican community were standardized for sex and prior international migration. The offspring of the exogamous matings were larger than those of the endogamous matings in 3 of 26 anthropometric dimensions. The probability of 3 or more in 26 dimensions at the 0.05 level is p = 0.14, not statistically significant. Comparisons of offspring of exogamous and endogamous unions in populations of this kind do not consistently provide evidence of heterosis.
