Synonymous mutations. These are mutations that happen in the coding regions of genes that change one nucleotide for another. However, because of redundancy in the genetic code (where one amino acid may be coded for by more than one nucleotide sequence) the amino acid sequence of the protein isn't altered.
Mutations that occur in non-coding, non-control regions of the genome also don't affect phenotype.

What else can I help you with?
How can you explain why mutations may or may not affect phenotype?
Mutations can affect phenotype by changing the genetic code, which can alter the way proteins are made and how they function in the body. However, not all mutations have a noticeable impact on phenotype, as some may occur in non-coding regions of DNA or may not change the protein structure significantly.
What does mutation rule states?
The mutation rule states that the state of mutations are in a mutated state when compared to a normal state. This is a slight mutation from the original stated rule.
How do lethal mutations and neutral mutations differ?
Lethal mutations cause such a radical change that the organism cannot live with it and dies. A neutral mutation is a simple change that does not affect the organism in any way, such as a new eye colour.
What are inactive alleles?
Inactive alleles are versions of a gene that do not produce a functional protein or have reduced activity due to mutations. These alleles may not contribute to the individual's phenotype or may have a diminished effect compared to active alleles. Inactive alleles can result in genetic disorders or variations in traits.
What is a mutation and how can it impact an individual's phenotype?
A mutation is a change in the DNA sequence of a gene. This change can alter the protein that the gene codes for, leading to changes in the individual's physical traits or characteristics, known as the phenotype. Mutations can have various effects on an individual's phenotype, ranging from no noticeable impact to causing genetic disorders or diseases.
Do mutations affect phenotype or genotype?
genotype always...phenotype sometimes
What is the conclusion of mutagenic effect of vodka on the phenotype of fruit fly?
some mutations include the change in eye color of the drosophila melanogaster
Do mutations always cause pheynotypic changes?
No, because of the redundancy in the genetic code (several base triplets or codons code for the same amino acid) a point mutation, for instance, (a change in one base) may have no effect on the amino acid sequence in the protein, and so no effect on the expressed phenotype.
How do mutation effect future generations?
Mutations can be passed on to future generations through genetic inheritance. Depending on the type of mutation, it can have varying effects on the offspring, from no impact to significant changes in the phenotype or overall health of the individual. Over time, these mutations can accumulate and contribute to genetic diversity within a population.
How can you explain why mutations may or may not affect phenotype?
Mutations can affect phenotype by changing the genetic code, which can alter the way proteins are made and how they function in the body. However, not all mutations have a noticeable impact on phenotype, as some may occur in non-coding regions of DNA or may not change the protein structure significantly.
What do mutations cause in genotype and phenotype?
Mutations can cause changes in the genotype by altering the DNA sequence. These changes can then affect the phenotype by influencing the expression of certain traits or characteristics in an organism.
What does mutation rule states?
The mutation rule states that the state of mutations are in a mutated state when compared to a normal state. This is a slight mutation from the original stated rule.
What is beneficial mutations?
Well, there is no specific type of mutation that is beneficial. They can be harmful, helpful, or have no effect at all.
Which mutation is the most dangerous?
There is no definite answer to this question many types of mutations can cause death and I'd say that's the most dangerous effect of a mutation. Large Scale mutations, like deletions or amplifications, usually cause the most damage because they effect whole chromosomes. Small Scale mutations are usually less dangerous because they only effect one gene. The worst small scale mutations are insertions and deletions because they change the reading frame. In my personal opinion, harmful mutations that occur in the tumor suppressor genes are the most dangerous because they are what prevent the mutations in cell from being duplicated and without them working a mutated cell can replicate uncontrollably.
Can mutation beneficial?
Yes mutations are the basis of evolution as they provide variance in the phenotype that could have evolutionary advantages
How can you have the same phenotype but different genotype?
Different genotypes don't always change your phenotypes because of mutations
How do lethal mutations and neutral mutations differ?
Lethal mutations cause such a radical change that the organism cannot live with it and dies. A neutral mutation is a simple change that does not affect the organism in any way, such as a new eye colour.
