An individual that is heterozygous for two linked genes has the genotype Ab/aB, which means that the A and b alleles are in one chromosome and the a and B alleles are on the homologous chromosome. Which of the products of meiosis listed are the recombinant types?

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.
