GCTA

GCTA, or Genome-wide Complex Trait Analysis, is a statistical method used in genetics to estimate how much of a trait—inherited characteristics like height or intelligence—can be explained by common genetic variations across the entire genome. It analyzes DNA data from many individuals to determine the proportion of variation in a trait that is due to shared genetics, providing insights into the genetic architecture of complex traits. This helps researchers understand the relative influence of genetics versus environment on traits within populations.
