Table 1. Summary of the results for the dynamics of phenotypic mean, variance, and allele frequency when the phenotypic optimum is suddenly shifted.
Mean dynamics determined by | Variance dynamics characterized by | Selective sweeps at major loci | |
---|---|---|---|
Small effects | Initial variance (18) | Small variations (19) | Unlikely (39) |
Large effects | Effect size (30) | Large variations (31) | Probable (41) |
