What else can I help you with?
Could a mutation affect phenotype?
Yes, a mutation can occur without affecting the phenotype at all. For example, a point mutation may change a nucleotide in a codon, but sometimes, the codon can still code the same amino acid, so the mRNA strand can still make the same protein.
Which gene mutation is less likely to result in a phenotype change and why?

What One example of a mutation that would not affect an organisms phenotype?
A silent mutation is an example of a mutation that would not affect an organism's phenotype. This type of mutation occurs in a non-coding region of DNA, such as an intron, and does not change the amino acid sequence of the protein produced. Therefore, it has no impact on the organism's outward appearance or characteristics.
What cell mutation does not impact the phenotype of the organism because the protein remains unchanged?
It is possible for a point mutation to not change the sequence of amino acids in a protein. This will result in the protein being unchanged and will not affect the phenotype.
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.
What causes a frequency in a population to change after each generation?
Gene mutation causes the phenotype frequency in a population to change after each generation.
What name do scientists use to describe a change in a gene?
Scientists use the term "mutation" to describe a change in a gene. Mutations can be caused by various factors and can result in a range of effects, from no noticeable change to significant alterations in the organism's characteristics.
A mutation in a gene may not affect an individual's phenotype because?
the mutation may occur in a non-coding region of the gene, resulting in no change to the protein produced. Additionally, the mutation may be silent, meaning it does not alter the amino acid sequence of the protein. In some cases, the organism may have redundant genes that compensate for the mutation, allowing it to function normally.
What is a example of a neutral mutation?
A neutral mutation would be something such as having one green eye and one blue eye. It doesn't hinder you and it doesn't give you an advantage.
What is a mutation called that has no effect on an organism?
A point mutation, in which one nitrogen base in a codon is substituted for another, may have no effect on an organism. This is true if the base substitution does not change the amino acid that the codon represents, or if the mutation occurs in a non-critical location in the protein so that the protein's structure is not changed significantly and the protein is still able to function.
What can occur as a result of a change in the sequence of nucleotides in a strand of DNA?
The addition or deletion of a nucleotide can lead to a Frameshift mutation. The Frameshift mutation causes a "shift" in the reading frame of the codons in the mRNA. This may lead to the change in the amino acid sequence at protein translation.
What is it called when a mutation occurs outside a gene?
When a mutation occurs outside a gene, it is referred to as a "regulatory mutation" or "non-coding mutation." These mutations can affect gene expression by altering regulatory elements such as promoters, enhancers, or silencers, which control when and how much a gene is expressed. Although they do not change the protein-coding sequence, they can still have significant effects on an organism's phenotype.
