Effects of interracial crosses on cephalometric measurements.

The effects of race and interracial crossing were examined on six cephalometric measurements among 9,912 schoolchildren in Hawaii. The measurements studied were face height, bizygomatic diameter, bigonial diameter, head breadth, head length, and cephalic index. Racial effects were studied in terms of general racial effect, maternal effect, and hybridity and recombination effects based on a model of diallel cross.
