Impact of Deep Coalescence on the Reliability of Species Tree Inference from Different Types of DNA Markers in Mammals

Figure 1

Scheme of the species tree used for computer simulations.

θ, present and ancestral population size parameters (here, assumed to be constant). τ, divergence times. x and y, length of internal branches. The MCcoal notation of this species tree corresponds to: “(((sp1_# θ1, sp2_# θ2): τ1 # θ12, sp3): τ2 # θ123, sp4): τ3 # θ1234;”. Both τ and θ are measured in substitutions/site.
