Phylogenetic Trees

Diagrams representing the evolutionary relationships among various biological species or entities based on similarities and differences in their physical and/or genetic characteristics.

Synonymous Sites

Locations in a gene where a mutation does not change the encoded amino acid, typically due to the redundancy of the genetic code.

Nonsynonymous Sites

Positions in a gene where changes in the DNA sequence lead to changes in the amino acid sequence of the encoded protein, potentially affecting its function.

Directional Selection

A form of natural selection in which one extreme phenotype is favored over other phenotypes, causing allele frequencies to shift in one direction.
