A change in genotype, but not in phenotype, is most likely due to neutral mutation.
A mutation consists of a spontaneous and unpredictable change in the sequence of genes that make up the DNA of a living being.
- A neutral mutation is one that has no consequences on the phenotype, that is, it has no effect on the observable characteristics of an organism.
- Neutral mutations has effects on the genotype because it generates a change in the order of nucleotides that creates triplets that code for equivalent amino acids as basic amino acids.
Therefore, we can conclude that a neutral mutation does not affect the viability of the living being.
