In contrast, because selection acts directly on phenotype, phenotypic divergence is generally touted as evidence in favor of selection.
Thus, functionally divergent genes might contribute to the phenotypic divergence in xylem formation.
Hence, the diploid hybrid exhibited phenotypic divergence from both parents, while the gynogenetic diploids were phenotypically indistinguishable from the maternal parent and had similar meristic counts.
Geographically isolated populations often show phenotypic divergence in traits important in reproduction.
The process of domestication results in genetically-based phenotypic divergence from wild populations, through both intentional and unintentional selection1,2,3.
The variations mapping to these GSVs may be among the causative mutations that have led to the phenotypic divergence between these two species.
Background: Sequence changes in regulatory regions have often been invoked to explain phenotypic divergence among species, but molecular examples of this have been difficult to obtain.
Quantitative genetics provides a framework for understanding how genetic variation within populations allows phenotypic divergence via genetic drift and natural selection.
The genetic basis of species differences provides insight into the mode and tempo of phenotypic divergence.
The implication is that competition and coevolution, by facilitating phenotypic divergence, have contributed to the reduction of gene flow between them and to their persistence over time.
Phenotypic divergence was greater than genetic divergence, indicating directional selection on some flight morphology traits.
