Moreover, the existence of paralogous genes seems to have facilitated divergence of imprinted genes.
Gene duplication facilitates functional divergence but functional constraints enable the retention of genes with overlapping or redundant functions.
Second, divergent infection levels should cause divergent selection and facilitate adaptive divergence.
The second prerequisite is that these infection levels cause divergent selection and facilitate adaptive divergence.
Multis are known for their complex dentition and unique locomotor adaptations, which facilitated their divergence into a suite of ecosystems.
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.
We found that they occurred independently at the regional scale, but co-occurred at the landscape scale, facilitated by divergence in seasonal resource use at the habitat scale.
Furthermore, there is increasing evidence for the presence of compartmentalization of HCV populations within infected patients [42] [47], which would further facilitate lineage divergence within a patient.
Chromosomal rearrangements could facilitate sequence divergence around the rearranged regions, thus indirectly contributing to recombination repression through the mismatch repair system [5], [34] [36].
