Yes, mutations can occur all over at the same time.
For example in a multicellular organism a gamma ray or x-ray photon passing through the organism can generate one or more mutations in every cell that the photon passes through.
Another example mutagenic chemicals can produce many mutations in every chromosome.

Could a single mutation cause barbules to form on feather barbs?
Although the cause of barbules to form on feather barbs doesn't sound like a difficult change in evolution, it would likely take more than just a single mutation for such an evolutionary change to occur. Most likely, it would take many mutations.
Which type of mutation will probably have a larger effect A point mutation or a frameshift?
Both types of mutation have the potential to cause a large effect.In general, a frameshift mutation is more likely to cause a large effect. This is because it shifts the 'reading frame' - so that all of the subsequent codons (groupings of 3 bases that are read to determine which amino acid will be added) will be changed.A point mutation is when a single base is replaced. This can either result in the same amino acid being added to the protein being synthesised (a silent mutation), a different amino acid being added (a missense mutation) or in a STOP codon (a nonsense mutation).If a point mutation causes a premature STOP codon - this is quite likely to have a large effect on the protein.
What does an abnormality in or mutation of a gene produce?
The simplest answer is variation or death. If the mutation is abberant enough it renders the organism nonviable...a continum of lesser effects that potentially result in deformity, disorder, pigment variation, behavioral change all the way to some fabulous modification that creates a great adaptation that makes an organism more successful.
A mutation is harmful to an organism if?
Mutations are harmful if they decrease the function of some part of the body. Unfortunately, this is the case far more often than them making an improvement.
Are Antibiotic resistance evolved through the process of natural selection acting upon random mutation?
Antibiotic resistance is developed as the organism grows more resistant to a chemical that doesn't kill it initially. In bacteria, this is a mutation and gives rise to various 'strains'.
How mutation affect survival skills of an organism?
It depends on the mutation. Some mutations have no effect on survival, some mutations are lethal, and some mutations make an individual better adapted to its environment, so it will be more fit than those without the mutation, and therefore produce more offspring with the same mutation, which could change the allele frequency of a population.
Which of the following could be described as a chromosomal mutation?
A chromosomal mutation can occur for a variety of reasons. Some people think that DownÕs syndrome is a mutation but it is more an additional chromosome than a mutation.
What are the factors that cause evolution to occur?
The two main factors are mutation and natural selection.Mutations are random changes in our DNA that cause changes. Some of these changes are bad, some are neutral, and some are good.This is where natural selection comes in. If the mutation is bad, then that organism is less likely to mate and pass down the gene. The organism dies along with the mutation that made it less fit. If it is neutral, which is what most mutations are, then nothing happens. If it is good, then the organism is more likely to survive and pass down the gene which will then propagate through the species.
Could a single mutation cause barbules to form on feather barbs?
Although the cause of barbules to form on feather barbs doesn't sound like a difficult change in evolution, it would likely take more than just a single mutation for such an evolutionary change to occur. Most likely, it would take many mutations.
What is the difference between multicellular organism and a single celled organism?
Single means 1... multi means more.... lets see if we use common sense a single cell organism has one cell and a multicellular organism has more than one cell.
What type of mutation is a beneficial to an organism?
Those that increase your health, your survival, your ability to have children and of course too many other benefits to name, here. Generally mutations are the key to natural selection. Beneficial mutations that occur allow an organism to survive longer, thus reproduce more, passing this mutated trait down to their offspring.
Which statement is more accurate to scientist the evolution of a single individual organism or the evolution of a whole species?
Single individuals are naturally selected, but populations ( can be whole species ) evolve. Any mutation happening in the germ line of an individual will die with him. Only his progeny can inherit said mutation and evolve. Evolution is the change in allele frequency over time in a population of organisms.
Why does a mutation in a sex cell affect an organism?
It only affects the offspring of the organism.
What is the mutation in hemophilia?
Hemophilia is a mutation of either of the genes that make factor VII or IX. Hemophilia A is a mutation of the F8 gene and Hemophilia B is the mutation of the F9 gene. Both of these mutations occur on the sex-linked X chromosome.
Why did evolution not occur in down syndrome?
Down Syndrome is a the addition of an extra chromosome and not really related to evolution. It is more of a genetic mutation that causes this event to occur.
Is a bee a single celled organism?
No it is a multi-celled organism. It contains more than one cell.
