Contrasting quantitative traits and neutral genetic markers for genetic resource assessment of Mesoamerican Cedrela odorata

摘要: We compared within-population variability and degree of population differentiation for neutral genetic markers (RAPDS) eight quantitative traits in Central American populations the endangered tree, Cedrela odorata. Whilst diversity (Shannon index) (heritability, coefficient additive variation) were uncorrelated, both marker types revealed strong between from Atlantic coast Costa Rica rest species' distribution. The interpopulation was higher RAPD (F-ST 0.67 sampled Mesoamerican range) than (Q(ST) = 0.30). Hence, divergence lower could have been achieved by drift alone, suggesting that balancing selection similar phenotypes different this species. Nevertheless, a comparison pair-wise estimates positive correlation (r 0.66) that, C. odorata, be used as surrogate adaptive gene conservation planning. utility finding suggested further work are discussed.
