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
22,404 correlation data on
796 traits, and
4,079 heritability data on
1,030 traits, in
5 livestock animal species have been curated
from 380 publications.
Database maintenance note: Feb. 24, 2021: 1,241 heritability data
entered prior to 2012 were recalled as part of our data quality assurance efforts.
If you found correlation data that has not been included in the current release,
please either (1) register for a curator account to directly input them (see
"Database Curators / Editors" below), or (2) inform our
Bioinformatics Team so that we can include your data for curation.
