Genome-wide linkage analysis using genetic variance components of alcohol dependency-associated censored and continuous traits.

abstract：:Hybrid designs arose from an effort to combine the benefits of family-based and population-based study designs. A recently proposed hybrid approach augments case-parent triads with population-based control-parent triads, genotyping everyone except the control offspring. Including parents of controls substantially impr...
