Estimation based on 1,000 replications, Exp: Expected number of loci with heterozygosity excess; Hex: Heterozygosity excess; IAM, infinite alleles model; TPM, 2-phase model (a combination of the IAM 30% and SMM 70%); SMM, stepwise mutation model. Significance at P < 0.05, with significant bottleneck effect indicated in bold
