When the distribution of phenotypes of polygenic traits is graphed, a bell-shaped curve is obtained. Expression of polygenic trait Frequency of Phenotype Phenotype Marissa and Gene have phenotypes at the opposite extremes of a polygenic trait. What phenotype will their children most likely have

What is the significance of the protein-lined pits? a. protein attracts other proteins needed for atp synthesis within the cell. b. protein-lined pits are able to transport one molecule at a time down the concentration gradient within the cell. c. the polarity of proteins allows other polar molecules to attach and be transported in the cell by transport channels. d. receptors within the pits allow ligands to fuse and be transported into the cell by endocytosis.
