    A silent gene is a mutant gene having no detectable phenotypic effect. It results from a silent mutation.Then, what is silent mutation?A silent mutation is that: a base pair substitution that alters an amino acid codon but still codes for the same aminoe acid due to degeneracy of the code. 簡單的說: silent gene 就是一種突變的基因, 而這種基因是由silent mutation所造成的而silent mutation 會影響 DNA transcription, 造成之後的蛋白質減短, 或者是沒有功用.
