WebPhenotypic correlations are likely to be fair estimates of their genetic counterparts in many situations. These further results also indicate that genetic and environmental causes of phenotypic variation tend to act on growth and development in a similar manner. © 1988 The Society for the Study of Evolution. WebPhenotypic values of different traits in the same trees are often correlated, such as height and diameter. Environmental factors and genetic effects are two reasons for correlations. Similar to partitioning phenotypic variance, we can decompose phenotypic correlation (r P) into its genetic (r A) and environmental (r E) components. r P = r A + r ...
