Answer:
one polypeptide.
Explanation:
Genes are the nucleotide sequence present in the DNA or RNA which are passed to the next generation and are responsible for giving some characteristics to the offspring.
According to the one gene one polypeptide hypothesis one gene is responsible for the synthesis of one polypeptide. Earlier it was thought that one gene synthesizes one enzyme but later it was found that gene also codes single polypeptides and non-enzyme proteins.
Therefore a single gene controls the synthesis of one polypeptide.
