  • a Δ, the marker interval length. The length of chromosome is 100 cM.

  • b Sampled distributions of models a–d corresponding to BC1, F2, and BC2 populations, respectively, are a, (N(1, 1), N(0, 1), N(–1, 1)); b, (N(0, 1), N(0, 1), N(0, 1)); c, (N(1, 1), N(0, 2), N(–1, 1)); d, (N(1, 2), N(0, 2), N(–1, 1)).

  • c The empirical thresholds are based on 5000 replications.

  • d Sparse map calculation of the theoretical threshold based on (1).

  • e Dense map calculation using (1) with v = 1(i.e., Δ = 0).

  • f Thresholds at 95% (99%).
