Animal Trait Correlation Database

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遗传相关（genetic correlation）是指两个性状间由遗传因素所导致的共享方差占比；表型相关（phenotypic correlation）则指群体内个体间两个性状共同变异的程度。在基因组学时代，尽管基因表达分析、遗传关联分析与网络分析为解析复杂表型的遗传基础提供了前所未有的手段，但我们仍需充分认识到单一性状的遗传进展可能对其他性状产生的潜在影响。本数据库旨在收录所有已发表的畜禽遗传/表型性状相关数据，以助力遗传网络分析或系统生物学研究。
