Additive genetic variance (VA) reflects the potential for evolutionary shifts and can be low for some traits or populations. High VA is critical for the conservation of threatened species under selection to facilitate adaptation. Theory predicts tight associations between population size and VA, but data from some experimental models, and managed and natural populations do not always support this prediction. However, VA comparisons often have low statistical power, are undertaken in highly… CONTINUE READING
