Randomized trial reveals correlations between gene expression and phenotypic characteristics in birds, suggesting genotype-phenotype relationships.

The analysis aims to explore how the patterns of developmental control gene expression correlate with phenotypic characters in adult birds.
Analyzed 42 skeletal measurements from two avian clades: finches (n=313) and pigeons (n=219).
Calculated observed and theoretical correlation matrices for each clade.
Used Mantel's test to compare observed and theoretical matrices to identify significant pattern correspondences.
17% of correlation patterns were significant in finches (P ≤ 0.05) and 63% in pigeons.
Multiple comparisons showed 15% of observed patterns explained in finches and 22% in pigeons at P ≤ 0.001.
Common correspondence between Gdf gene expression and limb length found in both clades.
