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.

Explain how mutations in gametes may result in phenotypic changes in offspring?
Mutations in gametes can lead to changes in the genetic code that can be passed on to the next generation. If these mutations occur within a gene that codes for a specific trait, such as eye color or height, it can result in a phenotypic change in the offspring. The new genetic information from the mutation can influence the development and expression of traits that may differ from the parents' traits.
How does a mutation in a sex cell differ from a mutation in a non-sex cell?
Mutations in sex cells can be passed on to children. Mutations in sex cells only affect offspring. Mutations in sex cells do not affect the organism.
What type of mutations do not effect phenotype?
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. You may also wish to look at Wikipedia's entry on silent mutations.
What is it called when DNA replication messes up?
One ma be born with physical, and or mental illness. Such as fragile X syndrome.
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.
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 does a mutation in a gene affect the order of DNA based?
A mutation in a gene can happen by addition, deletion or substitution of base pairs. This means that the order of the bases will change- a new base may be added, a base may be lost, or one base may be substituted for another. The result of these mutations is that it causes the DNA to code for a different protein. If a mutation occurs in a sex cell, the mutation can be passed on to an offspring and affect the offspring's phenotype.

What types of mutations occur during dan replication and do they cause genotypic and phenotypic changes in offspring?
During DNA replication, mutations can occur as point mutations (like substitutions), insertions, or deletions. These mutations can lead to changes in the genetic code, potentially resulting in genotypic changes that may also manifest as phenotypic changes in offspring. However, not all mutations affect the phenotype; some may be silent or neutral, while others can lead to beneficial or harmful traits. The overall impact on the offspring depends on the nature of the mutation and its effect on protein function.
Do all mutations affect the protein results?
No. Point mutations may have no effect on the protein, however, they can also be very harmful.
When genotypes are altered by mutations there is a new phenotype which is?
When genotypes are altered by mutations, they can lead to the expression of new phenotypes, which are the observable traits of an organism. These changes can affect various characteristics, such as physical appearance, behavior, or physiological functions, depending on the nature and location of the mutation. Some mutations may have beneficial effects, while others can be neutral or harmful. Ultimately, these phenotypic variations play a crucial role in the process of evolution and natural selection.

Why not all mutations are passed on to future offspring?
Not all mutations are passed on to future offspring because mutations occur randomly and may not affect an individual's reproductive cells. Additionally, some mutations may be harmful to the organism, reducing its chances of survival and reproduction. Finally, mutations that do occur in reproductive cells may not be passed on if the individual does not reproduce or if the mutation is not present in the germ line cells.
