Incomplete lineage sorting

Incomplete lineage sorting[1][2][3] is a characteristic of phylogenetic analysis where the tree produced by a single gene differs from the population or species level tree.[4]

Incomplete lineage sorting (ILS) occurs when a polymorphic ancestral species, with two or more alleles (haplotypes) at a given locus divides into two lineages. Both alleles can be retained in the descendant branches, and when one of those lineages divides again, the phylogenetic tree for that locus (the gene tree) may or may not match the branching order for the species-level evolutionary tree.[4]
