title: Hypodontia: a polygenic trait--a family study among Israeli Jews.
abstract: A high prevalence of hypodontia was detected among 820 first degree relatives of 305 probands and there was an increased risk if a second family member was affected. Hypodontia is a common trait in the population, and a deviation from normal sex ratio was observed in those affected. These results suggest a polygenic mode of inheritance.
