Phylogenetic Tree- Definition, Types, Steps, Methods, Uses
WebIf a phylogenetic tree is reconstructed from DNA sequence data of a particular gene, a hard polytomy arises when three or more sampled genes trace their ancestry to a single gene in an ancestral organism. In contrast, a soft polytomy stems from branches on gene trees of finite temporal duration but for which no substitutions have occurred. WebApr 28, 2024 · Cladogram Definition.
