Animal Traits Correlation Database (CorrDB)

Release 21
(Apr 29, 2024)

Animal Trait Correlation Database

Genetic and phenotypic trait correlation studies have been conducted for decades since Hazel proposed the methods in 1943. A genetic correlation is the proportion of shared variance between two traits that is due to genetic causes; a phenotypic correlation is the degree to which two traits co-vary among individuals in a population. In the genomics era, while gene expression, genetic association, and network analysis provide unprecedented means to decode the genetic basis of complex phenotypes, it is important to recognize the possible effects genetic progress in one trait can have on other traits. This database is designed to collect all published livestock genetic/phenotypic trait correlation data, aimed at facilitating genetic network analysis or systems biology studies.

As of the current Release, a total of 37,017 correlation data on 865 base traits and 992 trait variants; 6,264 heritability data on 1,090 base traits and 976 trait variants, in 6 livestock animal species have been curated from 628 publications.
