Estimates of nucleotide diversity (θ_π), Watterson's estimator (θ_W), Tajima's D and Ramos-Onsins and Rozas' population growth test (R₂) using gp60 and COWP genes for Cryptosporidium species infecting humans and other animal hosts (n ⩾ 4, the minimum number of sequences required to compute these tests). *P < 0.05, ***P < 0.001.
