Coalescent Gene Genealogies

​
n
10
The coalescent describes the genealogical relations of the lineages ancestral to a sample of genes. The sample size,
n
, may vary from 1 to 50 gene copies; each tree shows a possible genealogy among these copies with nodes representing the common ancestors of the sampled genes. The lengths of branches are randomly based on the probability of coalescence in a population of
2N
gene copies.
