The codon TCA codes for serine in a gene. If a new mutation occurred the replaced the "A" with "T" resulting in the production of the same amino acid this mutation would be a ___________ mutation and its fate over many generations would most likely be determined by _____________

Answer:

The correct answer is "silent; codon usage".

Step-by-step explanation:

Silent mutations are changes in the genome sequence that do not result in any observable change in the phenotype of the individual. A common silent mutation is the change of a nucleotide in a codon that results in another codon that is translated into the same amino acid. The fate of silent mutations over many generations is determined by the codon usage of the species. If the silent mutation results is a codon that is not normally used by the species, it is very likely that it will get lost over time.
