In domesticated dogs, size has a high heritability, and the trait is determined by only a small number of genes. In contrast, genetic variation at more than 3000 QTLs explains less than half of the high heritability for height in humans. Required:
What could explain the missing heritability in humans, and how could you test your hypothesized explanations?

the solute can move "downhill," from regions of higher to lower concentration, relying on the specificity of the protein carrier to pass through the membrane. this process is called passive transport or facilitated diffusion, and does not require energy.
