Yes, triplets come from the same fertilized egg or zygote, so they share the same DNA and are genetically identical. However, small variations can still occur due to epigenetic factors or random mutations.
Chromosome mutations are generally considered more severe than point mutations because they involve changes in a larger portion of genetic material, potentially affecting multiple genes and leading to more significant impacts on an organism's phenotype. Point mutations, on the other hand, involve changes in a single nucleotide and may have smaller-scale effects.
Mutations are random occurrences because they result from changes in the genetic material that are typically spontaneous and not influenced by any specific goal or plan. They can happen due to various factors such as exposure to mutagens or errors during DNA replication. As such, mutations are not a deliberate or controlled process but rather a natural phenomenon that contributes to genetic diversity.
It depends on the specific context. Point mutations typically involve a change in a single nucleotide, which may or may not lead to changes in the corresponding amino acid. Frame shift mutations, on the other hand, involve the insertion or deletion of nucleotides that can disrupt the reading frame of the gene, potentially leading to more drastic changes in the resulting protein. So, in general, frame shift mutations could be considered more harmful as they have the potential to alter multiple amino acids downstream of the mutation site.
You can cross fruit flies with different mutations, such as curly wings or ebony body color, to produce various mutant combinations. By crossing flies with different mutations, you can generate new mutant combinations and study their effects on traits and behaviors.
Mutations that occur at the beginning of the genetic code, such as frameshift mutations, tend to be more harmful than those at the end because they can alter the reading frame of the entire sequence, causing downstream changes in multiple codons and leading to a completely different protein being produced. In contrast, mutations at the end of the code, such as point mutations, may only affect a single amino acid or codon, resulting in less drastic consequences.
Mutations introduce new genetic variations into a population. Some mutations may provide individuals with advantageous traits that help them survive and reproduce better than others. Over time, these advantageous mutations can become more common in a population, leading to evolutionary changes.
I don't think so. Mutations are changes in the genetic material of a cell, and the cause of a mutation in most cases are either point mutations (only a single base pair in a DNA is involved) or chromosomal mutations (involve rearrangements in big regions of chromosomes). But changing rearrangements does not exactly change what is in the DNA itself, and small changes could not give special abilities since we know you need a lot of changes to become Spiderman In most cases, mutations tent to be harmful (causing cancer) rather than be helpful.

Because not every point mutation changes the protein. If it doesn't change, we call it a silent mutation or when one letter is deleted at the beginning, than the whole chain changes, but if it's at the end only the and changes so it's a bigger effect on the protein :p

Some mutations are neutral because an amino acid can be more than one anti-codon. However, mutations that do cause change can be good, bad, or neutral depending on how it changes its' form. I don't want to go over all of them!
A few years ago, biologists would have said that the relation between epigenetics and evolution was minimal, given that there was no reason to think, at the time, that epigenetic effects lasted more than a couple of generations. Now, however, it is becoming more apparent that epigenetic factors can indeed influence the way allele frequencies develop over the generations, and thus have a lasting impact on the evolution of a population.
Transitions are more common than transversions in genetic mutations because they involve a change between two nucleotides of the same type (purine to purine or pyrimidine to pyrimidine), which is structurally easier and more likely to occur than a change between nucleotides of different types.
