HFC comparisons following Szulkin et al. (2010) for both mesic and dry provenances of Swietenia macrophylla (Ĥj and σ2(Ĥj), heterozygosity mean and variance, respectively; f, inbreeding estimate derived from the MLTR selfing rate where f = s/(2 − s); g2, interlocus heterozygosity correlation inferred from RMES (David et al. 2007); r2ωj,Ĥj, the variation in fitness explained by heterozygosity; βωj,Ĥj, regression slope of fitness-heterozygosity regression; r2ωj,f, variation in fitness explained by inbreeding; βωj,f, regression slope of fitness-inbreeding, the inbreeding load; variance parameters in parentheses; g2 values followed by ‘*’ or ‘NS’ indicate significant and non-significant interlocus heterozygosity correlation respectively)
