2.1.4 | Recurring increasing admixture scenarios
For a given source population S, scenarios S-IN mirrors theS-DE scenarios by considering instead a recurring monotonically
increasing admixture from population S (Figure 1 , Table
1 ). Here, s S,g, with g in [1..20],
are the discrete numerical solutions of the same function as in the S-DE
decreasing scenarios (see above), flipped over time between generation 1
and 20. In these scenarios, s S,20 is defined in
[0,1] and s S,1 in
[0,s S,20/3], and u in [0,1/2]
parametrizes the “steepness” of the curvature of the increase. Note
the analogous nestedness of recurring and pulse-like scenarios over the
parameter space of u values as previously.
