Witryna5 wrz 2024 · As a result, many complex traits exhibit intimate correlation and tend to be tightly integrated, resulting in heritable covariation, which add the complexity for breeding. Therefore, an understanding of how traits co-variation is essential for the genetic improvement of multiple complex traits.
