Coalescence in a model with two diverging populations
At a time T in the past, the
ancestral population split into two populations. The
ancestry of a sample of two gene copies, one from each
population, is traced back to the MRCA (red). The
time to the MRCA (the coalescence time)
is t. Notice that in this example t
> T.
