Comparison of sequence diversity rates in meiotic recombination genes in Z. mays ssp. parviglumis and in tropical and temperate maize inbreds. a Nucleotide sequence diversity (π) in the coding region. Black bars indicate standard error values. b Amino acid sequence diversity (π a /π s ). In Spo11-1, all substitutions within the tropical as well as temperate inbred groups were non-synonymous and the π a /π s ratios could not be calculated for them. c Fixation index (FST) to measure genetic differentiation between temperate and tropical maize in coding regions of recombination genes
