  • All calculations are based on coding regions of genes. Only the third exon of MYB37 was amplified, which comprises > 70% of the entire ORF. Statistical significance of D was investigated by coalescent simulations. Nucleotide diversity (πtotal) at MAM2 is 0.0072 if we include alleles that have experienced gene conversion. NS, not significant.
