Sentence examples for large phenotypic changes from inspiring English sources
It proposes that both small and large phenotypic changes occur within the same species, and that the existence of alternative phenotypes within lineages facilitates macroevolution by reducing the negative fitness consequences associated with the appearance and fixation of large phenotypic variants [ 3].
If evolution cannot proceed by genetic changes with very small phenotypic effects, then how are the many potentially deleterious effects of large phenotypic changes avoided?
Thus, assuming that mutations in central genes have a high phenotypic impact, our results indicate that some large phenotypic changes, driven by promoter evolution, may have boosted the evolution of the human lineage.
Genomic variability between individual strains of bacteria may be small and well defined, but may cause large phenotypic changes.
Crop and livestock breeders often provoke relatively large phenotypic changes across successive generations conditioned on available standing genetic variation found in wild progenitor populations.
These results suggest that relatively few genes contribute to the large phenotypic changes seen among reference and resistant populations upon exposure to PAH pollutants.
In addition, the cytoplasmic genome controlled larger phenotypic changes than the nuclear locus within a cytonuclear interaction.
Overall, there were small changes in allele frequencies at individual loci over the studied time period; but, on average, the changes were greater in lines with larger phenotypic changes.
Body size showed the largest phenotypic change, on the order of nine phenotypic standard deviations, with approximately 11% of the change explained by adaptive plasticity.
We found three lines of evidence that suggest changes to a 'master switch' can result in large scale phenotypic changes: 1.
Many genetic studies link specific nonsynonymous mutations (which are usually alleles of relatively large phenotypic effect) to changes in phenotypes.
