Table 5 Models of variable ζ among sites
From: DNA polymorphism and selection at the bindin locus in three Strongylocentrotus sp. (Echinoidea)
Model | Free parameters | Site classes | Proportions of sites from a corresponding class |
|---|---|---|---|
Neutral | ζ0, p 0 | ζ0 < 1, ζ1 = 1 | p 0, p 1 = 1− p 0 |
Two-category | ζ0, ζ1, p 0 | ζ0 < 1, ζ1 ≥ 1 | p 0, p 1 = 1− p 0 |
